Hunting is not only to lower the population of a

Population explosion is the main obstacle to the smooth development of the Indian economy. Since this problem is getting intense day by day‚ it is obvious to take appropriate measures to keep it under control by lowering the birth rate. 1.Rise in Per-capita Income: Demographic history of various advanced countries shows that there is an inverse relationship between per-capita income and a country’s birth rate.
