Short & Long Question Answer: Population

Q1. What are the processes of population change or growth? Describe them.

Ans: Population change occurs through three main processes:

• Birth rates: This is the number of live births per thousand people in a year. When birth rates exceed death rates, a population increases naturally. In India, historically higher birth rates than death rates have been a major reason for population growth. Improvements in maternal care and infant survival also affect the number of births that contribute to population change.
• Death rates: This refers to the number of deaths per thousand people in a year. A decline in death rates - caused by better healthcare, improved nutrition, sanitation and disease control - increases the size of the population unless birth rates fall by a similar amount. The fall in death rates in India over recent decades has been a key factor in population rise.
• Migration: This is the movement of people either within the country (internal migration) or across international borders. Net migration (immigrants minus emigrants) changes the total population of a place. Internal migration does not change the country's total population but redistributes people, affecting regional population densities and social and economic conditions in source and destination areas.

Q2. "Distribution of population is uneven in India". Describe the factors responsible for it.

Ans: Uneven population distribution in India is marked by significant differences in population density across regions. The main factors responsible are:

• Physical factors: Relief, climate, soil and availability of water influence where people settle. For example, western Rajasthan has low population density because extreme temperatures and low rainfall make agriculture and living difficult. In contrast, the Indo-Gangetic plains (including cities such as Patna and Kanpur) are densely populated because of fertile soil and plentiful water.
• Economic opportunities: Areas with industries, services and trade attract people for jobs. Cities such as Mumbai, Delhi and Bengaluru have high densities because they provide jobs, education and services.
• Transport and infrastructure: Good roads, railways and ports encourage settlement and trade. Regions with poor connectivity often remain sparsely populated.
• Historical and social factors: Traditional patterns of settlement, land use, and social structures also shape population distribution. Coastal areas and river valleys that supported early civilisation tend to remain densely inhabited.

Q3. Which regions of India have moderate population densities and which regions have high to very high population densities? Why?

Ans: Assam and most of the peninsular states of India generally have moderate population densities. Factors contributing to moderate density in these regions include:

• Hilly and rocky terrain that restricts large-scale agriculture and dense settlements.
• Low to moderate rainfall in some parts of the peninsula which limits intensive farming.
• Shallow and less fertile soils in many areas of the peninsular plateau.

In contrast, the Northern plains and Kerala have high to very high population densities because of:

• Flat plains with fertile soils suitable for intensive agriculture and high food production.
• Abundant rainfall and extensive irrigation systems that support farming and settlements.
• High levels of urbanisation and better economic opportunities in some dense regions, adding to population concentration.

Q4. The substantial improvement in the health conditions of the Indian population is the result of many factors. What are these factors?

Ans: Health is an important component of population composition and has improved in India due to several factors:

• Improvement in public health measures such as better sanitation, safe drinking water in some areas and hygiene awareness campaigns.
• Prevention of infectious diseases through widespread vaccination programmes (for example, against polio and measles) and public health drives.
• Application of modern medical practices including improved diagnostics, medicines and surgical care which have reduced mortality from many diseases.
• Focused programmes for maternal and child health, family planning and nutrition have helped reduce infant and maternal deaths.

Q5. What did the National Population policy 2000 do for the adolescent population of India?

Ans: The National Population Policy 2000 recognised adolescents as a crucial demographic group requiring special attention. Key elements of the policy for adolescents included:

• Nutritional needs: Emphasised improving nutrition to support growth and development in adolescents.
• Delayed marriage: Promoted programmes that encourage later marriage and childbearing to improve health and educational outcomes.
• Sex education and awareness: Aimed to provide adolescents with information about reproductive health, risks of unprotected sex and prevention of sexually transmitted infections.
• Access to services: Sought to make contraceptive and reproductive health services more accessible and affordable for adolescents, along with information on life skills and counselling.

Q6. Write a note on India's population distribution by density.

Ans: Population density gives an idea of how people are spread over an area and highlights uneven distribution. It is calculated as the number of persons per square kilometre. Important points about India's population density are:

• India is one of the most densely populated countries in the world.
• In 2011, the national population density was 382 persons per sq. km.
• There are wide differences among states: for example, Bihar had about 1,102 persons per sq. km, while Arunachal Pradesh had only around 17 persons per sq. km.
• High densities in some states place pressure on land, water, housing and public services, while low densities in others reflect difficult terrain or limited economic opportunities.

Q7. Look at the following table carefully. What does it indicate? What can be done to turn the sex ratio in favour of females? The Magnitude and Rate of India's Population Growth

Ans: The table indicates that the sex ratio in India has generally been unfavourable to females. For example, there were 946 females per 1,000 males in 1951 and this figure showed little improvement in some decades, remaining a concern as late as 2011 when it was 940 females per 1,000 males. This imbalance reflects social preferences for sons and other discriminatory practices.

To improve the sex ratio in favour of females, the following measures can be taken:

• Promote education for girls and boys to change attitudes and raise awareness about gender equality.
• Run public awareness campaigns to highlight the social and economic value of female children.
• Strictly enforce laws against sex-selective practices, including the PCPNDT Act, and penalise those who misuse medical technology for prenatal sex determination.
• Provide incentives and support schemes for the girl child, improve female health services and ensure better access to education and employment for women.

Q8. Why is the health situation still in matter of major concern for India?

Ans: Despite progress in many areas, several problems keep the health situation in India a major concern:

• Malnutrition and low calorie consumption: Many people, especially children and women, do not get adequate calories and nutrients, which leads to stunting and other health problems.
• Limited access to clean water and sanitation: A large section of the rural population still lacks safe drinking water and proper sanitation, which increases the risk of water-borne diseases.
• Shortage of healthcare resources: Many regions face a lack of sufficient qualified doctors, nurses, primary health centres and hospital facilities, and public health infrastructure is unevenly distributed.
• High out-of-pocket medical expenses and unequal access to quality care mean that many people cannot afford treatment. Communicable diseases, maternal and child health challenges and emerging non-communicable diseases together continue to strain the health system.
