Q & A

What is the main focus of the chapter on population in geography?

The chapter emphasizes the relationship between population and geography, highlighting how human activities influence and are influenced by geographic resources.

As of March 2011, what was the population of India, and how does it compare globally?

India's population was approximately 1.21 billion, constituting 17.5% of the world's population while occupying only 2.4% of the world's land area.

Why is population distribution in India considered uneven?

Population distribution is uneven due to varying resource availability and environmental conditions, with states like Uttar Pradesh having a high population density compared to states like Sikkim.

What is the significance of population density, and how is it measured?

Population density indicates the number of people living per unit area, and it is measured by dividing the total population by the total area. In India, the average density is 382 people per square kilometer.

How do birth rates and death rates contribute to population growth in India?

Population growth is influenced by higher birth rates and declining death rates. The birth rate has increased over time, while improvements in healthcare have led to lower death rates.

What role does migration play in the population dynamics of India?

Migration, particularly from rural to urban areas, significantly affects population composition and distribution, as people move in search of better living conditions and job opportunities.

What is the adolescent population, and why is it important for India's future?

The adolescent population, aged 10-19, is crucial as they represent the future workforce of the country. Their development in terms of education and health is vital for national progress.

What key objectives are outlined in the National Population Policy of 2000?

The National Population Policy aims to provide basic education for children aged 6 to 14, reduce infant mortality rates to below 30 per 1,000 live births, and promote delayed marriages for girls.

How has the annual growth rate of India's population changed since 1981?

Since 1981, the annual growth rate of India's population has declined, indicating a slower increase in population even though the total number continues to rise due to lower death rates and higher birth rates.

What factors contribute to high population density in certain Indian states?

High population density in states like Bihar can be attributed to factors such as fertile land, favorable climatic conditions, and better employment opportunities, leading to more people settling in these areas.
