Due to large-scale improvement and development in medical facilities, the average age of a person in the world has increased. In many countries including India, the death rate has decreased, but there is no fall in the birth rate. Thus the total population is increasing every year. This has created many problems like unemployment and shortage of food houses, transport, water supply, etc. Now all the countries are making sincere efforts to control the growth of population. People are encouraged to follow the two-child norm. They are advised to have small families. A smaller population will help our country and the world to develop faster.
