2. Answer the following questions briefly.
a. Why is the rate of population growth in India declining since 1981?
Answer – There are several reasons why the population growth rate in India has been declining since 1981. One of the main reasons is the increasing prevalence of contraception and family planning initiatives. In the 1970s, the Indian government launched a campaign to promote the use of contraception and family planning in an effort to reduce the country’s high fertility rate. This campaign was successful in increasing the use of contraception and lowering the fertility rate.
Another reason for the declining population growth rate in India is the increasing trend of later marriage and childbearing. Many women in India are now delaying marriage and childbearing until later in life, which has led to a decrease in the number of children being born.
b. Discuss the major components of population growth.
Answer – There are two major components of population growth: natural increase and net migration.
Natural increase refers to the difference between the number of births and the number of deaths in a population. If the number of births in a population is greater than the number of deaths, the population will experience natural increase. If the number of deaths is greater than the number of births, the population will experience natural decrease.
Net migration refers to the difference between the number of people entering a population (immigrants) and the number of people leaving a population (emigrants). If the number of immigrants is greater than the number of emigrants, the population will experience an increase due to net migration. If the number of emigrants is greater than the number of immigrants, the population will experience a decrease due to net migration.
c. Define age structure, death rate and birth rate.
Answer – Age structure refers to the distribution of a population by age and gender. It is usually presented as a population pyramid, which is a graphical representation of the age and gender distribution of a population. A population pyramid can show the proportion of the population that is male or female, and the proportion of the population that falls into different age groups.
Death rate, also known as mortality rate, is the number of deaths in a population over a certain period of time, typically a year. It is usually expressed as the number of deaths per 1,000 people.
Birth rate, also known as fertility rate, is the number of live births in a population over a certain period of time, typically a year. It is usually expressed as the number of live births per 1,000 people.
d. How is migration a determinant factor of population change?
Answer – Migration is a movement of people from one place to another, and it can be a significant determinant of population change. If there is net migration into a population, it will result in an increase in the size of the population. If there is net migration out of a population, it will result in a decrease in the size of the population.
Migration can have a variety of different causes, including economic, social, political, and environmental factors. People may migrate in search of work or to be with family, or they may be driven to migrate by conflict, persecution, or natural disasters.
3. Distinguish between population growth and population change.
Answer – Population growth refers to an increase in the size of a population over time. It can be caused by a variety of factors, including high fertility rates, low mortality rates, and net migration.
Population change, on the other hand, refers to any change in the size, composition, or distribution of a population. In addition to population growth, population change can also refer to population decline (a decrease in the size of a population) or changes in the age, gender, or spatial distribution of a population.
4. What is the relation between occupational structure and development?
Answer – Occupational structure refers to the distribution of the working-age population within a country or region by occupation. It can provide insights into the economic development of a region or country, as well as the types of jobs and industries that are prevalent in the region.
In general, as a country or region develops and its economy grows, its occupational structure tends to shift from one dominated by agriculture and other primary sector occupations to one dominated by manufacturing and other secondary sector occupations.
5. What are the advantages of having a healthy population?
Answer – There are many advantages to having a healthy population. Some of the main benefits include:
- Increased productivity: Healthy individuals are more likely to be able to work and be productive, which can contribute to the economic development of a country.
- Improved quality of life: Good health allows individuals to participate in activities that they enjoy and lead fulfilling lives.
- Reduced healthcare costs: A healthy population is less likely to require medical care, which can help to reduce healthcare costs.
- Increased life expectancy: Good health can help individuals to live longer, healthier lives.
- Stronger social connections: Good health can help individuals to maintain strong social connections with their families and communities.
6. What are the significant features of the National Population Policy 2000?
