A Study of India Population Growth Rate Structure in Last 5 Years

India 2024 population is estimated at 1,450,935,791 people at mid-year. India population is equivalent to 17.78% of the total world population. India ranks number 1 in the list of countries and dependencies by population. The population of India is expected to increase from 121.1 crores to 151.8 crores during the period 2011-2036 - an increase of 25 percent in twenty- five years at the rate of 1.0 percent annually. As a consequence, the density of population will increase from 368 to 462 persons per square kilometer. A change in the age structure of the population changes the dependency ratio. A group of people between the ages of 0 and 14 who depend on other people for survival are dependent people. The ratio between 15 and 65 of these dependents is the dependency ratio. An increase or decrease in the dependency ratio affects the GDP  of  a  country.  GDP increases  if  the dependency ratio decreases. Population growth deals with the annual change in total population, and is affected by factors such as fertility, mortality and migration.
