Detailed explanation-1: -Demography is not one of the factors that play a role in the population growth rate. Demography is a study of human population. The other choices such as immigration, death rate and emigration are some of the factors that play a role in the populatoon growth rate.
Detailed explanation-2: -Control in birth rate is not responsible for the population growth in India. A high birth rate will consequently result in high population growth. Birth rate gives the number of children born in a period of time.
Detailed explanation-3: -When demographers attempt to forecast changes in the size of a population, they typically focus on four main factors: fertility rates, mortality rates (life expectancy), the initial age profile of the population (whether it is relatively old or relatively young to begin with) and migration.
Detailed explanation-4: -Population growth rate is affected by birth rates, death rates, immigration, and emigration. If a population is given unlimited amounts of food, moisture, and oxygen, and other environmental factors, it will show exponential growth.
Detailed explanation-5: -Climate is not a social factor affecting the population distribution. Climate, topography and soil are geographical factors.
