Exam Tip: Be precise with numerical data and the specific year mentioned in the question for reports like the Human Development Report.

Question 5. When economic development takes place in a country
(a) Contribution of agricultural sector decreases.
(b) Contribution of agricultural sector increases.
(c) Contribution of industrial sector decreases.
(d) Contribution of service sector decreases.
Answer: (a) Contribution of agricultural sector decreases.
In simple words: When a country develops economically, the share of farming in its total economy usually goes down. More people move to working in industries and services.

Exam Tip: Economic development often involves a structural transformation of the economy, moving from primary (agriculture) to secondary (industry) and tertiary (services) sectors. Understand this common pattern.

Question 6. What is the maximum value of Physical Quality of Life Index (PQLI)
(a) less than 100
(b) more than 100
(c) 100
(d) zero
Answer: (c) 100
In simple words: The highest possible score you can get on the Physical Quality of Life Index (PQLI) is 100. This means the best performance in all areas it measures.

Exam Tip: Know the range and maximum/minimum values for different development indices (e.g., PQLI, HDI) as these are fundamental characteristics.

Question 7. What is the value of Human Development Index?
(a) 0
(b) 1
(c) between 0 & 1
(d) 100
Answer: (b) 1
In simple words: The Human Development Index (HDI) is measured on a scale, and its highest possible value is 1. This number shows the maximum level of human development.

Exam Tip: Be aware of the scaling for different indices. HDI typically ranges from 0 to 1, while PQLI is often from 0 to 100.

Question 8. Generally which countries are related with the concept of economic growth?
(a) Developed
(b) Developing
(c) Backward countries
(d) Third world countries
Answer: (b) Developing
In simple words: Economic growth usually refers to countries that are still developing, focusing on increasing their output. Developed nations tend to focus more on broader economic development.

Exam Tip: Economic growth is often a primary goal for developing countries, as it involves increasing production and income. Developed countries typically prioritize sustainable development and quality of life improvements.

Question 9. Economic development is the _____ of economic growth.
(a) Cause
(b) Result
(c) Means
(d) End
Answer: (b) Result
In simple words: Economic development is the outcome or effect that often comes after economic growth. Growth can lead to development, but development is a wider concept.

Exam Tip: Understand the causal relationship: economic growth can *lead* to economic development, but development encompasses more than just growth. Development is a broader, more qualitative process.

Question 9. ___ was first in Human Development Index according to 2014 report.
(a) Japan
(b) Norway
(c) America
(d) India
Answer: (b) Norway
In simple words: In the 2014 report for the Human Development Index, Norway held the top position. This indicates Norway had the highest level of human development that year.

Exam Tip: For HDI rankings, it's useful to know which countries consistently rank high (e.g., Norway) to understand benchmark performance.

2. Answer the Following Questions in One Line:

Question 1. What is Economic growth?
Answer: Economic growth is the sustained increase in an economy's total output over a long period. This means there is a continuous rise in real national income and real per capita income, which defines economic growth.
In simple words: Economic growth is when a country produces more goods and services over time, leading to higher national income and income per person.

Exam Tip: When defining economic growth, remember to mention "long run" and "real national/per capita income" to make your answer complete and precise.

Question 2. Give the meaning of Economic development?
Answer: Economic development is a process through which a nation improves the economic, political, and social well-being of its population. It involves broad changes that enhance people's lives.
In simple words: Economic development is how a country gets better overall, improving the lives of its people in economic, political, and social ways.

Exam Tip: Emphasize that economic development is a holistic concept, covering economic, political, and social aspects, unlike economic growth which is primarily quantitative.

Question 3. What is per capita income?
Answer: Per capita income is the number calculated by dividing the total national income by the total population of a country. It represents the average income per person.
In simple words: Per capita income is simply the national income divided by the total number of people, showing the average income for each person.

Exam Tip: Always mention the formula or method of calculation when asked to define terms like per capita income, as it clarifies understanding.

Question 4. Why is per capita as an indicator is more effective than national income as an indicator?
Answer: The 'per capita income' considers the population size, which national income does not. This inclusion makes per capita income a superior indicator of development because it reflects the average individual share of wealth, providing a clearer picture of living standards.
In simple words: Per capita income is better because it includes the population, giving a clearer idea of income per person, while national income doesn't.

Exam Tip: Highlight the "population factor" as the key advantage of per capita income over national income in assessing development accurately.

Question 5. Which economist presented the Physical quality of life index?
Answer: Morris Davis Morris presented the Physical Quality of Life Index (PQLI). He developed this index to measure well-being beyond just economic figures.
In simple words: Morris Davis Morris was the economist who created the Physical Quality of Life Index.

Exam Tip: Associate key figures with their contributions. Morris Davis Morris and the PQLI is a specific connection to remember.

Question 6. How many countries were included in the HDI of 2014?
Answer: 188 countries were included in the Human Development Index (HDI) report of 2014. This large number offers a broad global comparison.
In simple words: The Human Development Index for 2014 covered 188 countries.

Exam Tip: Specific numbers related to the scope of major reports like HDI are important facts to recall.

Question 7. Which factors are included in the Human Development Index?
Answer: The Human Development Index includes these factors:
1. Life expectancy
2. Education
3. Income
In simple words: The Human Development Index (HDI) measures development using three main things: how long people live, how much education they get, and their income.

Exam Tip: Remember the three core components of the Human Development Index (HDI): a long and healthy life (life expectancy), knowledge (education), and a decent standard of living (income).

Question 8. What is Infant mortality rate?
Answer: Infant mortality rate is the number of babies who die out of every 1000 live births before they complete their first year of life. It serves as an important health indicator.
In simple words: Infant mortality rate is how many babies out of 1000 are born but die before their first birthday.

Exam Tip: Define infant mortality rate precisely by including "per 1000 live births" and "before completing their first year" to ensure accuracy.

Question 9. State the maximum value in Human Development Index.
Answer: The maximum value of the Human Development Index (HDI) is 1. This represents the highest possible level of human development.
In simple words: The highest score you can get on the Human Development Index is 1.

Exam Tip: Be clear that HDI ranges from 0 to 1, with 1 being the optimal value. Contrast this with indices that may use a 0-100 scale.

Question 10. What does high per capita income indicate?
Answer: A high per capita income indicates that significant economic growth has occurred in the country. When considered as a development indicator, an increase in per capita income suggests an increase in development, showing improved average living standards.
In simple words: High per capita income shows strong economic growth and more development because people, on average, have more money.

Exam Tip: While high per capita income often signals development, always acknowledge that it's an average and doesn't fully capture income distribution or social welfare.

Question 11. Sanitation facility indicates which aspect of improvement?
Answer: Sanitation facilities represent a qualitative aspect of improvement. They reflect the quality of life and public health standards, rather than just economic output.
In simple words: Good sanitation shows better quality of life and health in a qualitative way.

Exam Tip: Differentiate between quantitative indicators (like income) and qualitative indicators (like sanitation, health, education) when discussing development aspects.

3. Answer the Following Questions in Brief:

Question 1. State the limitations of National Income as an indicator.
Answer: Using the growth rate in national income to show economic development has several limits, which are discussed below:
1. Difficulty in calculating the true national income:
Problems like double counting, goods made for personal use, challenges in figuring out depreciation, illegal earnings, tax evasion, barter deals, illiteracy, and people working in multiple jobs make it hard to accurately estimate a country's real national income. Therefore, national income cannot be seen as a truly accurate way to measure economic development.
2. Population:
Knowing a country's national income alone is not enough to understand its rate of economic development. The country's population size should also be known. By considering population, we can say that if the national income growth rate is lower than the population growth rate, then development is negative. Similarly, if the national income growth rate is higher than the population growth rate, then economic development is positive. Since the national income method does not account for population and its growth, it is not a true indicator of economic development.
3. Different methods of calculating national income:
Various methods are used worldwide to calculate national income. The most important methods include:
(a) Production method
(b) Income method
(c) Expenditure method
The way national income is measured changes based on the calculation method used by each country. Different countries use different ways to calculate national income. This makes comparing economic development through national income difficult.
In simple words: National income is not a perfect way to measure development because it's hard to calculate accurately, it doesn't consider population changes, and different countries use different calculation methods, making comparisons difficult.

Exam Tip: When listing limitations, provide clear explanations for each point. For national income, focus on calculation issues, population impact, and comparability challenges across countries.

Question 2. State the limitations of per capital income as an indicator.
Answer: Here are the limits of per capita income as an indicator:
1. Only estimates:
The national income of the economy is figured out almost every year, so we get quite accurate data. However, the population count is not done every year. In India, a population census occurs once every 10 years. So, for the other 9 years, we just use an approximation of the population. Per capita income is found by dividing gross national income by the population. Since we do not get an exact population count every year, per capita income gives us an estimated number for all those years when we do not count the population.
2. Difficulty in calculating national income and per capita income:
Deciding whether per capita income should be figured out at current prices or constant prices, and the related difficulties, make it tough to know the real situation of per capita income and, therefore, development.
(3) Per capita income shows only an average:
We get per capita income simply by dividing national income by the population. This means that per capita income only shows an average income. We cannot decide at which stage our development is just based on this average. If income distribution among the population has happened fairly, then we can say that a rise in per capita income shows development. However, if fair distribution has not taken place, then a rise in per capita income does not mean an increase in economic development. Therefore, per capita income as a development indicator is not truly suitable.
4. Difficulty in comparison:
Countries report their per capita income in their own currency. This makes it hard to compare at an international level. To compare the per capita income of various countries, it must first be changed into US dollars. Once this is done, we can compare the economic development of different countries. Moreover, different countries worldwide have various controls on their exchange rates. Hence, the real exchange rate cannot be known, making it impossible to make a true comparison between countries.
5. Per capita income of the country is not the actual income that a citizen receives. Per capita income as an indicator hides more than it shows, and therefore it is not a correct indicator.
In simple words: Per capita income has limits because it's often based on estimates, it's hard to calculate consistently, it only shows an average income without showing how it's distributed, and it's difficult to compare across different countries. It doesn't always reflect what people actually earn.

Exam Tip: When discussing per capita income limitations, focus on its nature as an average, the challenges of accurate population data, and the complexities of international currency comparisons. Also, stress that it doesn't reveal income distribution.

Question 3. Where do the quantitative and qualitative changes occur?
Answer:
• Both quantitative and qualitative changes are features of economic development. Economic development involves an increase in 'output,' which is a quantitative change.
• Thanks to research and innovation, the quality of products, a qualitative aspect, also improves. However, it should be noted that there is more qualitative improvement rather than just quantitative change during development.
In simple words: Quantitative changes, like more production, and qualitative changes, like better product quality, both happen during economic development. Quality improvement is often more significant.

Exam Tip: When explaining quantitative and qualitative changes, clearly link them to economic development and provide brief examples to illustrate each type of change.

Question 4. What type of change is rise in production?
Answer: A rise in production represents a quantitative change. It means that an economy is making more goods and services. This type of change is easy to measure using numbers, like the total amount of goods produced or the value of those goods. While important for economic growth, a rise in production does not always mean there is an improvement in the quality of life or the social well-being of people. It is a key part of economic growth but not the full picture of economic development.
In simple words: A rise in production is a quantitative change, meaning it's about making more goods and services, which can be measured with numbers.

Exam Tip: Clearly state that a rise in production is a quantitative change, and explain why it is measurable using numerical data.

Question 5. What are the various indicators of Economic development?
Answer: Several indicators are used to measure economic development, each offering different insights into a country's progress. Key indicators include the growth rate of national income, which shows the overall increase in economic output. Another important indicator is the growth rate of per capita income, which considers income per person, giving a better sense of individual prosperity. The Physical Quality of Life Index (PQLI) looks at non-economic aspects like life expectancy, infant mortality, and literacy. Finally, the Human Development Index (HDI) combines life expectancy, education, and standard of living to offer a broader view of human well-being and development. These are often presented in numerical and statistical terms to show progress.
• Growth-rate of national income
• Growth-rate of per capita income
• Physical Quality of Life Index (PQLI)
• HDI - Human Development Index
• GDF - Gender Development Index
• TAI - Technological Achievement Index
• HPI - Human Poverty Index
• HCI - Human Consumer Index
In simple words: Economic development is measured by different things like how much the national income grows, how much income each person has, and indexes like PQLI and HDI that look at people's quality of life and education.

Exam Tip: When asked for indicators, list the main ones and briefly explain what each measures (e.g., national income, per capita income, PQLI, HDI). Remember to mention both economic and social indicators.

Question 6. State the limitations of Economic growth.
Answer: The limits of economic growth are:
• Economic growth only looks at quantitative change, meaning it focuses solely on numbers.
• In economic growth, there is a rise in 'national income' and 'per capita income'. Only important aspects such as institutional and psychological factors do not show any rise.
• The idea of economic growth is narrow and only shows the rise in the rate and extent of output.
• The concept of economic growth is not very helpful in understanding the well-being of people.
In simple words: Economic growth has limits because it only measures how much output increases and focuses on numbers like income, not on broader social improvements or people's overall well-being.

Exam Tip: When discussing limitations of economic growth, emphasize its narrow, quantitative focus and its failure to capture qualitative aspects of human well-being and social factors.

Question 7. State the limitations of development.
Answer: Here are the limits of economic development:
1. Economic development is a much broader idea than economic growth. It includes the ability to reflect a nation's progress. But in actual sense, it cannot tell about the human development that is happening. Whether human progress has happened or not cannot be known from economic development alone.
2. We cannot measure economic growth in the same way we measure economic development. The reason for this is that economic development includes changes that have happened in society. It is very hard to measure what changes have happened and the exact method to measure them.
3. When economic development occurs, people's standard of living improves. Now, even though economic development is taking place in India today, there isn't much improvement in people's standard of living. Hence, we cannot say that economic development always means an improvement in living standards.
In simple words: Economic development is hard to measure because it's a broad concept, it includes social changes that are difficult to quantify, and sometimes improvements in living standards don't keep up with other development indicators.

Exam Tip: When outlining limitations of development, highlight its broad, multi-dimensional nature, which makes it complex to measure accurately, especially qualitative aspects and social progress.

Question 8. What is life expectancy at birth?
Answer: Morris included three indicators, or determinants, to measure the physical quality of life. These three determinants are:
1. Literacy
2. Life expectancy
3. Infant mortality rate
Thus, PQLI = Literacy level + Life expectancy index + Infant mortality index.
The three factors (determinants) of Physical Quality of Life

After 2003, three more aspects were included in PQLI, and the Quality of Life Index (QLI) was prepared worldwide.
In simple words: Life expectancy at birth is the average number of years a baby is expected to live from the moment they are born. It's an important health indicator.

Exam Tip: Ensure you define life expectancy accurately as "at birth" and its meaning as an average. Also, remember its role as one of the key determinants in PQLI.

Question 9. Between growth and development, which one is difficult to measure? Why?
Answer:
• Development is harder to measure compared to growth. Growth refers to quantitative change, which is always easy to measure. Growth is measured by statistical numbers and indicators such as per capita income, national income, and so on.
• Development is more of a qualitative aspect. It covers areas like how much people's living standards have improved or how much their health has improved. It is quite difficult and a lengthy process to measure such aspects.
In simple words: Development is harder to measure than growth because growth is about numbers and quantities, which are easy to count. Development is about qualities and improvements, which are much tougher to measure.

Exam Tip: Clearly articulate that development's qualitative nature makes it harder to measure than growth's quantitative nature. Provide examples for each to strengthen your explanation.

4. Give Answers to the Point for the Following Questions:

Question 1. What is Physical Quality of Life? What are the aspects included in it?
Answer: Physical Quality of Life:
• The physical quality of human life depends on the various types of goods and services that a person uses over a period.
• The 'standard of consumption' refers to the use of goods and services by a person or group of people during a specific time.
The consumption includes:
1. Consumption of food, fuel, and other non-durable goods
2. Consumption of durable and semi-durable goods
3. Consumption of service goods/use of services
• The standard of consumption, or standard of living, determines the physical quality of life.
• If people's living standards rise, it can be said that their physical quality of life has improved.
Aspects included in the Physical Quality of Life:
• The types of goods and services an individual uses during one year determines their physical quality of life.
Following are the determinants included in the list of goods and services:
1. Food (Proportion of calories, protein, and fats)
2. Health and medical services (Proportion of doctor to population)
3. Housing and clothing (Number of rooms in a house, average number of people living in each room, etc.)
4. Education and entertainment (percentage of population getting primary, secondary, education, entertainment facilities like TV, theatre, etc.)
5. Transport, communication, and information services (the extent of road, railway lines, number of telephones per capita.)
6. Energy (Per capita energy consumption)
7. Population having access to pure drinking water
8. Average life expectancy
9. Infant mortality rate
10. Drainage facility
If there is an improvement in these 10 aspects or determinants, then we can say that there is improvement in the physical quality of human life. On the contrary, if improvement has not happened, then these determinants can be studied and analyzed to see where improvement is needed and what steps should be taken to increase the rate of development. Every indicator can be shown relatively. The value of each indicator is equally shown on a scale of 0 to 100.
• The indicator with the highest value is given 100 points.
• Note that developed countries give more importance to improving the physical quality of life.
In simple words: Physical Quality of Life is about the goods and services people use, showing their living standards. It includes things like food, health, housing, education, transport, energy, clean water, life expectancy, infant mortality, and drainage.

Exam Tip: Define PQLI by linking it to consumption and living standards. Then, list the specific aspects or determinants clearly, as they are crucial for a complete answer.

Question 2. Discuss national income as an indicator of economic development.
Answer: Growth-rate of national income:
• National income as a development indicator suggests that a country has achieved economic development if there is a continuous increase in its real national income over a long period.
• According to this indicator, if the national income rises quickly, the development rate is high. If the rise is slow, the development rate is low. Moreover, if national income does not rise, it means the country's development is stuck. If national income decreases, it shows underdevelopment or negative development.
• For calculating this indicator, 'real income'—not 'money (nominal) income'—is considered. As a result, national income is calculated at constant prices, not current prices.
Tabular representation of national income as an indicator of development:
• Some countries have a quicker growth rate of national income compared to others. Hence, we can also say that economic development will be quicker in such countries.
• The table below shows that countries like Norway, America, Sri Lanka, and Pakistan have a slower annual growth rate of national income compared to India.
• Although India is currently considered one of the fastest developing countries globally, it should be noted that countries like Norway and America have already grown significantly in the past. Hence, their current growth appears smaller (2% to 3%) compared to India's 7.3%.

In simple words: National income shows development if it keeps rising over time, especially "real income" at constant prices. High growth means high development. However, simply comparing current growth rates can be misleading if older, developed countries had higher growth in the past.

Exam Tip: When discussing national income as an indicator, explain how it signals development, clarify the use of "real income" at "constant prices," and use comparative data (like the table) to illustrate its strengths and potential misinterpretations.

Question 3. Explain per capita income as an indicator of economic development.
Answer: Per capita income as an indicator of economic development:
• The figure found by dividing a country's gross national income by its total population is called per capita income. In other words, per capita income is the average income per person.
• As seen in the definition, 'per capita income' also takes population into account. Hence, this development indicator is better than 'national income'.
• According to this indicator, when a country's per capita income continuously increases for a long period, it can be said that economic development has happened.
• The UNO (United Nations Organization) has suggested per capita income as an indicator of economic development.
• If per capita income is high and its growth rate is also high, then we can say that development has taken place.
• If the country's per capita income rises faster, development is fast. If per capita income grows slowly, development is slow. If per capita income stays constant, there is stagnation, and if per capita income falls, development is negative.
• The main goal of economic development is to improve people's standard of living and boost human development. Per capita income is one of the best indicators for achieving this.
• When we say development has happened, we mean that people's standard of living has improved. If this has not improved, then we cannot say that development has happened in a real sense.
• Now, a rise in per capita income improves an individual's physical welfare, making it a true indicator of economic development.
Tabular representation of per capita income as an indicator of development: Per-capita national income of few countries in 2014

In simple words: Per capita income is a good indicator of development because it considers income per person, is recommended by the UN, and shows how fast development is occurring. A continuous rise in per capita income usually means better living standards and overall human welfare.

Exam Tip: When explaining per capita income, define it clearly, highlight its advantage over national income (population consideration), state its relationship to development speed, and acknowledge its role in improving living standards. Using a table for comparison can further illustrate its application.

Question 4. Explain in brief, the limitations of Physical Quality of Life Index.
Answer: Limitations of PQLI:
1. PQLI uses only three indicators for its calculation. Relying on only these three indicators doesn't truly show if a country has developed or not. To gain an accurate view, we should also include other relevant factors.
2. PQLI only provides an average score. Following the PQLI equation, the scores from the three indicators are divided by 3 to get an average PQLI. An average of three country aspects doesn't highlight the strength or weakness of each specific indicator. Therefore, making choices based solely on averages is not ideal.
In simple words: PQLI uses only three indicators and gives an average score. This means it doesn't give a full or detailed picture of a country's development or show the individual strengths and weaknesses of each factor.

Exam Tip: When discussing limitations, ensure you clearly state why each point is a drawback and how it affects the accuracy of the index as a measure of development.

Question 5. At present, India is growing or developing or both. Give answer by stating reasons.
Answer:
1. Currently, India is seen as one of the world's fastest developing economies. Looking at the growth information, India's national income in 2014 increased by 7.4%. This rate is significantly higher than that of even very developed nations like Norway and America.
2. Likewise, if we examine per capita income, India's per capita income increased by 6% in 2014. India's percentage growth in per capita income is quite high compared to highly developed countries such as Norway and America, which show growth rates of 1.1% and 1.6% respectively.
3. Based on these numbers, one can confidently say that India has achieved significant economic growth. However, this alone does not mean India is a developed country.
4. The 2014 Human Development Index indicated India's HDI was 0.609, placing it 130th among 180 countries. This rank is much lower than nations like Norway and America, despite their slower growth in national and per capita income compared to India. Consequently, even with strong economic growth, India remains significantly behind in overall development.
5. Even though economic progress is happening in India now, there hasn't been significant betterment in the people's living standards.
6. Therefore, India remains a developing nation that needs to advance considerably before it can be called a developed nation.
In simple words: India is experiencing economic growth with high national and per capita income increases. However, its low Human Development Index rank and lack of significant improvement in living standards mean it is still a developing nation, not yet developed.

Exam Tip: Clearly distinguish between economic growth (quantitative increase) and economic development (qualitative improvements in living standards and human well-being) in your answer, providing specific data points and HDI rankings for support.

5. Answer the following questions in detail:

Question 1. Explain with the help of examples, the difference between economic growth and economic development.
Answer: The difference between economic growth and economic development can be understood from the following discussion.
Economic growth:
• When we use the word 'growth', it specifically refers to 'economic growth'.
• Economic growth is defined as the long-term increase in an economy's total output.
• Total output here means a steady rise in the country's real national income and real per capita income, which we refer to as economic growth.
• This kind of growth occurs because of an increased supply of production factors such as land, capital, labor, and people's entrepreneurial skills, along with higher productivity from these factors.
• When the supply, availability, productivity, and efficiency of production factors grow continuously, it results in an increase in 'real national income' and 'real per capita income'. This increase is known as economic growth. Since income increases can be counted and observed, we view economic growth as a 'quantitative change'.
• A nation's economic standing can be assessed by understanding its economic growth. The pace of economic growth also enables us to compare different countries' economies.
Economic development:
• Economic development occurs when there's a steady increase in an economy's total output through real national income and real per capita income (quantitative aspects), alongside improvements in qualitative aspects.
• Economic development is a broader concept than 'economic growth'. It involves an ongoing, multifaceted process covering economic growth, people's well-being, and overall economic advancement.
• When we talk about economic development happening, it means the country is also advancing in its economic and social structures, not just in financial terms.
• So, during economic development, improvements in society happen alongside overall economic advancement.
• Changes are also evident in the national income structure. The percentage contribution of agriculture to total national income goes down, while the share from industrial and service sectors rises.
• People who are underemployed in the agricultural sector find jobs in other industries.
• The country begins to utilize advanced technology, which helps save time and money, thereby boosting productivity.
• New seed varieties are also developed for farming in the country. This alters the institutional framework, which then transforms production and distribution methods.
• Gradually, there is a decrease in poverty, joblessness, and disparities.
Conclusion:
• Economic growth is a limited concept, primarily focused on increasing real national income and per capita income. However, economic development is a broader idea that, beyond growth objectives, also seeks to achieve the social well-being of its citizens.
• Less developed nations initially focus on achieving economic growth. After reaching a certain point, they then begin to pursue economic development.
In simple words: Economic growth is about things getting bigger, like more money or more production, which you can count. Economic development is a wider idea; it's about things getting better, like people's lives improving, and society making progress, which includes both bigger numbers and better quality.

Exam Tip: For detailed explanations, start by defining each concept separately, then highlight their differences with specific examples like quantitative vs. qualitative changes, and how they relate to a country's overall progress and social welfare.

Question 2. Explain an improvement in the Physical Quality of Life Index as an indicator of economic development.
Answer: Physical Quality Life Index (PQLI):
• Increases in national income and per capita income have several drawbacks. Thus, these are not the sole true indicators of economic development.
• If a country's income has grown, but this increase benefits only a small group of people, it cannot truly be called development.
• A country's progress should ensure that the living conditions of less fortunate people improve and the fundamental needs of all residents are met.
• With these factors in consideration, Morris Davis Morris created the Physical Quality of Life Index (PQLI).
• PQLI aims to assess a nation's quality of life or overall well-being. This index considers an improvement in the physical quality of human life as economic development.
• To create the PQLI index, the level of physical quality of life (PQL) is found using several indicators.
• When a nation's physical quality of life is greater than another's, that nation is regarded as more advanced.
• Morris incorporated three indicators, or factors, to assess the physical quality of life. These three factors include: 1. Literacy, 2. Life expectancy, and 3. Infant mortality rate.
• So, PQLI is calculated by adding the literacy level, life expectancy index, and infant mortality index.
The three factors (determinants) of Physical Quality of Life:

Exam Tip: When explaining PQLI, clearly list its three core indicators and explain how each contributes to assessing the physical quality of life. Also, highlight why it's considered a more comprehensive indicator than simple income measures.

Question 3. What are the factors included in the human development index? Explain them.
Answer: Determinants of Human Development Index:
• For simplicity, HDI is created using three primary factors: (1) Life expectancy, (2) Education, and (3) Income.
• Life expectancy indicates the anticipated number of years a child will live from birth; education data illustrates societal achievements, while income data shows the living standards.
• It is important to remember that when calculating HDI, instead of using exact values, an average of all three indicators is used.

Exam Tip: When explaining HDI factors, remember the acronym 'LEI' (Life Expectancy, Education, Income) and briefly describe how each component is measured to assess human development.

Question 4. Compare PQLI and HDI and show which indicator is superior? Why?
Answer:
1. PQLI was created to address the many shortcomings of earlier measurement scales.
2. It was decided to establish an index that would use combined indicators to assess development, focusing on how well the basic requirements of most people are met, or in relation to their 'quality of life'. This decision resulted in the creation of a new index called the Physical Quality of Life Index.
3. Morris D. Morris formulated a unified, combined index using three key indicators: life expectancy at one year of age, infant mortality, and literacy.
4. For every indicator, a country's performance receives a score from 1 to 100; 1 signifies the 'poorest' performance, and 100 means the 'best' performance.
5. After a country's performance in life expectancy, infant mortality, and literacy is scored on a 1 to 100 scale, the nation's composite Physical Quality of Life Index (PQLI) is then found by averaging these three ratings, with each given equal importance.
Limitation of PQLI and development of HDI:
1. A significant drawback of PQLI, however, is its inability to include various other social and psychological factors implied by the phrase 'quality of life'.
2. This index has also faced criticism because it lacks proper justification for giving equal importance to all three indicators, and for the likelihood that measures like life expectancy and infant mortality essentially show the same thing.
3. The Human Development Index (HDI) was created to address the shortcomings of PQLI and other indicators.
4. The UNDP describes human development as "a process of expanding people's options." This relies on more than just income, including other social indicators. In contrast, PQLI examined social indicators individually.
5. The three core indicators are: long life, education, and a good standard of living. A long life is measured by life expectancy at birth; education is assessed by combining the adult literacy rate, and living standard is measured by GDP per capita (in US$ using purchasing power parity).
6. Before computing the HDI, an index must be created for each aspect: life expectancy, education, and income. Performance for each aspect is shown as a value between 0 and 1.
7. The literacy index and gross enrolment index are weighted two-thirds and one-third, respectively, to get the education index. The HDI is then figured out as a straightforward average of these three components.
8. Nations are subsequently grouped into three types: 1. High human development (HDI of 0.800 or more), 2. Medium human development (HDI between 0.799-0.500), and 3. Low human development (HDI below 0.500).
9. The great thing about HDI is that once income growth goes past a certain point, its impact lessens, making social indicators vital for shaping the HDI. Thus, this index aligns with the increasing global focus on human development.
10. Unlike other indexes that measure exact levels, the HDI ranks countries by comparing them. This index considers the progress achieved from the lowest point to the highest.
11. The progress made is shown as a percentage. This clearly illustrates the significant differences in human development between developing and developed countries.
12. This same process is applied to the index's other two parts. The progress for each component then serves as the foundation for combining the three measures, providing a consistent way to rank nations on a single scale.
Therefore, considering how HDI is calculated and the indicators it includes, we can confidently state that HDI is superior to PQLI.
In simple words: PQLI uses three basic factors like literacy and life expectancy, while HDI also uses three factors but includes income per person. HDI is better because it captures more social and economic aspects, measures real progress from minimum to maximum, and is more widely accepted for comparing human development across countries.

Exam Tip: To compare PQLI and HDI effectively, first define both, list their respective indicators, and then clearly articulate why HDI is generally considered superior, emphasizing its comprehensive nature, wider acceptance, and more nuanced approach to development measurement.

Question 5. Explain in short the indicators of economic development.
Answer: Indicators of development:
• A numerical measure that displays a country's progress in areas like health, education, and gender equality is recognized as a development indicator.
• These indicators serve as benchmarks or criteria to assess whether a country has advanced, and if so, to what extent.
• These measures, which gauge the pace and scope of economic development, can be expressed numerically and statistically.
Here are some indicators of development:
1. National income: Using national income as a development indicator, a country is considered to have achieved economic development if its real national income consistently increases over a long period.
• Based on this indicator, if national income rises quickly, development is considered high; if it rises slowly, development is low.
• Furthermore, if national income does not increase, the country's development is considered stagnant, while a decrease in national income points to underdevelopment or negative progress.
• To figure out this indicator, 'real income' is used instead of 'money (nominal) income'. Therefore, national income is calculated at constant prices, not current prices.
2. Per capita income:
• Per capita income is the value obtained by dividing a country's gross national income by its total population. Simply put, it's the average income per person.
• As stated in its definition, 'per capita income' also includes population. Therefore, this development indicator is considered better than 'national income'.
• Based on this indicator, if a country's per capita income steadily rises over an extended period, it shows that economic development has occurred.
• The UNO (United Nations Organization) has suggested using per capita income as an indicator for economic development.
• If per capita income is substantial and its growth rate is also high, then we can conclude that development has occurred.
• If a country's per capita income increases quickly, development is considered rapid. If it grows slowly, development is slow. If per capita income stays the same, it means stagnation, and if it decreases, development is negative.
• The main goal of economic development is to enhance people's living standards and promote human advancement. Per capita income is one of the most effective indicators for achieving this goal.
• When we state that development has occurred, we mean people's living standards have improved. If this betterment hasn't happened, then true development has not occurred.
• So, an increase in per capita income enhances an individual's physical well-being, making it a true indicator of economic development.
3. Physical Quality of Life Index (PQLI):
1. National income and per capita income have several shortcomings. Therefore, these two are not the sole accurate indicators of economic development.
2. If a country's income grows, but this increase benefits only a small group, then it cannot truly be considered development.
3. A country's progress should ensure that the living conditions of less fortunate people improve and the fundamental needs of all residents are met.
4. With these factors in consideration, Morris Davis Morris created the Physical Quality of Life Index (PQLI).
5. PQLI aims to assess a nation's quality of life or overall well-being.
6. This index views improvements in human physical quality of life as economic development.
7. To create the PQLI index, the level of physical quality of life (PQL) is found using several indicators.
8. When a nation's physical quality of life is greater than another's, that nation is regarded as more advanced.
9. Morris incorporated three indicators, or factors, to assess the physical quality of life. These three factors include: 1. Literacy, 2. Life expectancy, and 3. Infant mortality rate. So, PQLI is calculated by adding the literacy level, life expectancy index, and infant mortality index.
4. Human Development Index:
• The most current indicator for development is the Human Development Index.
• When the United Nations Development Programme (UNDP) released the Human Development Report (HDR) in 1990, it also brought in the Human Development Index as a way to measure development.
• HDI stresses both financial and non-financial measurements.
• Indian economists have also greatly helped in developing the HDI.
• This index is created by assessing each country's efforts toward its own development.
• In 2010, the minimum and maximum values for HDI were updated. Since that time, these new figures have been used to calculate HDI.
Determinants of Human Development Index:
• For simplicity, HDI is created using three primary factors: 1. Life expectancy, 2. Education, and 3. Income.
• Life expectancy indicates the anticipated number of years a child will live from birth; education data illustrates societal achievements, while income data shows the living standards.
• It is important to remember that when calculating HDI, instead of using exact values, an average of all three indicators is used.
In simple words: Indicators of economic development are ways to measure a country's progress. Key indicators include national income and per capita income, which show how much money a country and its people have. Other important indicators are the Physical Quality of Life Index (PQLI), which looks at health and education, and the Human Development Index (HDI), which combines life expectancy, education, and income to give a full picture of human well-being.

Exam Tip: When asked to explain indicators in short, focus on naming the primary indicators (National Income, Per Capita Income, PQLI, HDI) and providing a concise, one-sentence explanation for what each measures regarding economic development.
