POPULATION:A group of individuals or items that share one or more characteristics from which data can be gathered and analyzed.POPULATION GROWTH: Change in population over a period of time.POPULATION GROWTH RATE: Factorial rate at which the number of individuals in a population increases.GROWTH RATIO = GROWTH RATE * 100
Factors affecting Population Growth RatesPopulation growth depends on rates ofbirth, death, immigration, and emigration. (birth rate + immigration rate) – (death rate + emigration rate) = population growth rate
There are just three sources of change in population size —1. Fertility2. Mortality ―Natural Decrease" refers to population decline resulting from more deaths than births3. Migration Net migration is the number of immigrants minus emigrants

Overpopulation is a hindrance in the path of India’s economic development. Family planning awareness should be sown among the younger generations. Smaller families contribute to the well being of the individual as well as to India’s economy. India’s vast population puts a lot of stress on the economic infrastructure. It is high time that we Indians took measures to control this escalating population for the progress of our economy, our country.
