Q. C. : What are the problems in areas of high population densities?
Ans : Population density means the number of people living in a certain area.

Formula:
Population Density = Total Population ÷ Total Area

Problems of high population density:

1. Pollution: More people cause air, water, and land pollution. Due to an increase in land degradation by making houses and flats, land pollution will be caused, water will be contaminated by a huge number of people, resulting in water pollution and huge number of vehicles will cause air pollution.
2. Overcrowding: Too many people create noise, stress, and disturbance.
3. Less open space: Parks and open areas become very limited.

Q. d. : What arc the problems in area of low population densities?
Ans: The development of a country depends upon its size of population. A lower population is somehow manageable and resources can be distributed equally. But, sometimes the low population leads to lower demands of goods and services and lower tax revenues for the government to provide goods and services.

4. Give geographical reasons:

Q. a.: Population is an important resource.
Ans: The economic and cultural progress of a country depends on the number of people and their skills and abilities.
If a country has too many people but low skills and education, its development is slow.
If a country has the right number of people with good education and skills, it grows faster.
Therefore, population is a very important resource.

Q. b. : Productive population is an important group.
Ans : People between 16 and 59 years are called the productive population because they can work.
– People below 16 years and above 60 years are called the dependent population because they do not usually work.
– The productive population works in jobs, services, and businesses, so they help the economy grow.
– If a country has more young and productive people, it develops faster.
Therefore, the productive population is very important.

Q. c. : The study of age structure is important.
Ans: The study of age structure helps us understand how many children, young people, adults, and old people are in the population.
– It helps to know how many people are working (16–59 years) and how many are dependent (below 16 and above 60 years).
– It helps the government to plan education, health, jobs, and welfare schemes.
– It helps to understand how fast a country’s economy can grow.
So, the study of age structure is important.

Q. d. : Literacy is directly related to development.
Ans: A country with a high literacy rate grows faster in economic, social, and cultural areas.
– A country with a low literacy rate faces many problems in its growth and development.
– Literacy improves quality of life, gives more opportunities, and increases freedom.
Therefore, literacy is directly linked to development.

Q. e. : The real progress of a country is understood with the help of the Human Development Index.
Ans: The Human Development Index (HDI) is measured using information about income, health, and education.
– It is calculated using Gross National Product, life expectancy, and literacy rate.
– HDI shows the standard of living, quality of life, and well-being of people.
So, the real development of a country is understood through the Human Development Index.

5. Write notes.

Q. a. : Sex ratio.
Ans: Sex ratio means the number of females for every 1,000 males.
Formula:
Sex Ratio = (Number of females ÷ Number of males) × 1000

– If there are fewer females per 1,000 males, the sex ratio is low.
– If there are more females per 1,000 males, the sex ratio is high.
– According to Census 2011, Kerala had the highest sex ratio (1084).
Maharashtra had a sex ratio of 929.

Q. b. : Age structure.
Ans: Age structure means dividing the population according to different age groups.
– It helps us know how many children, young people, adults, and old people are in the population.
– It also helps to understand how many people are working (16–59 years) and how many are dependent (below 16 and above 60 years).
– Age structure helps the government make proper plans and policies.

Q. c. Literacy.
Ans: People above 7 years of age are divided based on their ability to read and write.
– Those who cannot read and write are called illiterate, and those who can are called literate.
– A high literacy rate shows good social and economic development, while a high illiteracy rate slows down development.
– Literacy improves quality of life, gives more opportunities, and increases freedom, so it is directly linked to development.
