Answer:
1. Meena
2. 66%
3. 888
In simple words: These blanks complete facts about Rajasthan's population, like its most common tribe, how many people can read, and the number of girls compared to boys. These numbers help us understand the state better.

🎯 Exam Tip: Always pay close attention to numerical data and specific names for fill-in-the-blanks questions. Make sure to use the exact terms or numbers.

Question 4. Why has the 'Beti Bachao, Beti Padhao' Yojna been launched?
Answer: The 'Beti Bachao, Beti Padhao' scheme was started in 2015. Its main goals are to keep women safe and to help them become strong and independent. The program aims to make women financially and socially self-reliant by giving them education. This initiative ensures that girls are valued and have equal opportunities.
In simple words: This plan was started to protect girls and help women become educated and independent, both financially and in society.

🎯 Exam Tip: When explaining government schemes, mention the year of launch and the core objectives related to social welfare or development.

Question 5. What does population change mean?
Answer: Population change means if the number of people in a place goes up or down. This change happens because of three things: births, deaths, and people moving in or out (migrations). If more people are born than die, the population grows. If more people die than are born, it shrinks. Also, when people move to a new place (immigration) or leave their old place (emigration), this also changes the population count. So, these three factors together decide if a population increases or decreases.
In simple words: Population change is about how the number of people in an area goes up or down. It depends on how many babies are born, how many people die, and how many people move in or out.

🎯 Exam Tip: Always list the three main factors (births, deaths, migration) when asked about population change and briefly explain how each contributes.

Question 6. Explain with an example the formula of determining population growth rate.
Answer: Let's use Rajasthan as an example to understand how to find the population growth rate.
First, we need the population at two different times. For Rajasthan:
1. Population in 2011: 68,548,437
2. Population in 2001: 56,507,188
3. The time difference between these two years is 10 years (2011 - 2001).
Now, we use a formula to calculate the growth rate. This formula compares the change in population to the earlier population, then multiplies by 100 to get a percentage.
\( \text{Population Growth Rate} = \frac{\text{Population in 2011} - \text{Population in 2001}}{\text{Population in 2001}} \times 100 \)
\( \implies \text{Population Growth Rate} = \frac{68548437 - 56507188}{56507188} \times 100 \)
\( \implies \text{Population Growth Rate} = \frac{12041249}{56507188} \times 100 \)
\( \implies \text{Population Growth Rate} = 0.2131 \times 100 \)
\( \implies \text{Population Growth Rate} = 21.31\% \)
So, Rajasthan's population grew by 21.31% in that decade (10 years). This shows the rate at which the population increased over a specific period.
In simple words: To find how fast the population grew, you subtract the old population from the new population, divide by the old population, and then multiply by 100. For Rajasthan, the population grew by 21.31% in ten years.

🎯 Exam Tip: Clearly state the population values for different years and the time difference. Ensure the formula is correctly applied, subtracting the older population from the newer one in the numerator.

Question 8. What does sex-ratio mean? Explain it with reference to Rajasthan.
Answer: Sex-ratio tells us how many females there are for every one thousand males in a specific area. This number helps us understand the position of women in society. According to the 2011 population census, Rajasthan had a sex-ratio of 928. This means there were 928 females for every 1000 males. However, for children under six years old, the sex-ratio was even lower, at 888. The sex-ratio tends to be higher in societies where women are respected and have a recognized role. If women are seen as less important than men, the sex-ratio will usually be lower.
In simple words: Sex-ratio is the number of females per 1000 males. In Rajasthan, it was 928 in 2011, and 888 for young children. A higher ratio usually means women are more respected in that society.

🎯 Exam Tip: Define sex-ratio accurately, state the specific numbers for Rajasthan, and link it to the social status and recognition of women.

Question 9. Write a note on the scheduled tribes in Rajasthan.
Answer: Most scheduled tribes in Rajasthan live in villages, in hilly areas, on plateaus, and in forests. They primarily earn their living through farming, doing manual labor, and collecting products from the forest. These tribes are spread across various districts, starting from Sirohi and extending through Bundi, Kota, Tonk, Sawaimadhopur, Jaipur, Udaipur, Dungarpur, Chittorgarh, and Banswara. The main scheduled tribes in Rajasthan are the Bhil, Garasiya, Meena, and Saharia. Among these, the Meena tribe has the largest population. The Saharia tribe is unique because it was recognized as an early Tribal group by the Government of India. The Bhils are considered the oldest tribe in Rajasthan, often speaking dialects related to Dravidian or Munda languages, known as Vagadi or Bheel. They also depend on farming and forest work. Almost half of the Meena people live in Jaipur, Dausa, Sawaimadhopur, Karauli, and Udaipur districts. The word 'Saharia' comes from the Persian word 'Sahar,' which means a jungle or forest, reflecting their close connection to nature.
In simple words: Scheduled tribes in Rajasthan live in rural and forest areas, working as farmers, laborers, or collecting forest items. Key tribes include Meena (largest), Bhil (oldest), Garasiya, and Saharia (first recognized). Their lives are closely connected to nature and traditional practices.

🎯 Exam Tip: When describing scheduled tribes, include their geographical distribution, main occupations, names of prominent tribes, and any unique characteristics or government recognitions.

Multiple Choice Questions

Question 1. What does the term population distribution means?
(a) Population in a specified area changes over time.
(b) The number of people who die in relation to the number of people born in a specified area.
(c) The way in which people are spread across a given area.
Answer: (c) The way in which people are spread across a given area.
In simple words: Population distribution simply means how people are spread out or arranged in a certain place. It shows where many people live and where fewer people live.

🎯 Exam Tip: Remember that "distribution" refers to spread or pattern, while "change" refers to increase or decrease, and "density" refers to numbers per unit area.

Question 2. If the birth rate of a country is more than the death rate, its population
(a) will increase
(b) will decrease
(c) will remain constant
(d) None of the options
Answer: (a) will increase
In simple words: If more babies are born than people die, then the total number of people in the country will become bigger. It's like adding more people than you lose.

🎯 Exam Tip: Understand that population growth is a net result; if additions (births) are greater than subtractions (deaths), the total increases.

Question 3. What are the three main factors that cause population change?
(a) births, deaths and marriage.
(b) births, deaths and migration
(c) births, deaths and life expectancy.
Answer: (b) births, deaths and migration
In simple words: The three main things that make a population change are how many babies are born, how many people die, and how many people move in or out of a place. These three factors directly influence the total count of people.

🎯 Exam Tip: Always remember the core demographic factors: natality (births), mortality (deaths), and mobility (migration) when discussing population changes.

Question 4. Complete the sentences- When people are attracted to an area it becomes..................populated. Factors that influence this include...........climate, good supplies of resources and...........land.
Answer:
1. densely
2. favourable
3. natural
In simple words: When a place is good for living, many people move there, making it densely populated. Things like good weather, plenty of resources, and suitable land make a place attractive.

🎯 Exam Tip: For sentence completion, identify keywords that describe reasons for settlement, such as "densely populated" for high attraction and "favourable climate" for good conditions.

Question 2. What is density of population?
Answer: Population density is the number of people living in a specific area of land. It tells us how crowded or spread out the people are. For example, it might be measured as people per square kilometer.
In simple words: Population density is simply how many people live in one square unit of land. It shows if a place is crowded or not.

🎯 Exam Tip: Define population density by mentioning "number of persons" and "per unit of land" to score full marks.

Question 3. What is birth rate?
Answer: Birth rate refers to the total number of live births that happen for every one thousand people in a given population over a certain period. This helps measure how quickly new individuals are being added to a population.
In simple words: Birth rate is how many babies are born for every thousand people.

🎯 Exam Tip: Always specify "live births" and "per thousand people" in your definition of birth rate.

Question 4. What is death rate?
Answer: Death rate is the number of deaths that occur for every one thousand people in a particular population during a specific time. It indicates how many people are being removed from the population.
In simple words: Death rate is how many people die for every thousand people.

🎯 Exam Tip: Similar to birth rate, define death rate by mentioning "number of deaths" and "per thousand people."

Question 5. What is migration?
Answer: Migration is the movement of people from one place to another, which can be either into an area or out of an area. This movement often involves changing one's place of residence permanently or for a long period.
In simple words: Migration means when people move from one place to live in another.

🎯 Exam Tip: Briefly explain that migration involves movement *into* (immigration) and *out of* (emigration) an area, affecting population counts.

Question 6. Which two districts of Rajasthan have the highest density of population?
Answer: The two districts in Rajasthan with the highest population density are:
1. Jaipur
2. Bharatpur
These districts often have better resources and opportunities, attracting more people.
In simple words: Jaipur and Bharatpur are the two districts in Rajasthan where the most people live per square kilometer.

🎯 Exam Tip: For questions asking for specific names, ensure you list all required items accurately, such as the two districts in this case.

Question 7. Which part of Rajasthan has less density and why?
Answer: The answer provided talks about population growth rate, not density. Based on the provided content: Jaisalmer and Barmer are districts with a population growth rate of more than 30%. In contrast, districts like Sriganganagar, Jhunjhunu, and Pali have a growth rate of less than 15%. This shows varying rates of population increase across the state, with some areas growing much faster than others.
In simple words: Some parts of Rajasthan, like Jaisalmer and Barmer, have a very high population growth rate (over 30%). Other parts, like Sriganganagar, have a much lower growth rate (under 15%).

🎯 Exam Tip: When discussing regional population characteristics, be specific about the areas and the related demographic indicators (e.g., growth rate, density, sex-ratio).

Question 9. Name the districts of Rajasthan with the highest and the lowest sex-ratio (two in each case).
Answer: Here are the districts of Rajasthan with the highest and lowest sex-ratio:
1. Two districts with the highest sex-ratio are:
(a) Dungarpur (994)
(b) Rajsamand (990)
2. Two districts with the lowest sex-ratio are:
(a) Dhaulpur (846)
(b) Jaisalmer (852)
These numbers show the variation in the number of females per thousand males across different parts of the state.
In simple words: Dungarpur and Rajsamand have the most females per male (highest sex-ratio). Dhaulpur and Jaisalmer have the fewest females per male (lowest sex-ratio).

🎯 Exam Tip: Clearly list both the districts and their corresponding sex-ratio numbers when asked for specific data points like this.
