India has a population of about 1. 32 billion. Its population is the second largest in the world. China has the largest population of about 1.37 billion. One out of six people on this planet live in India. Although, the crown(王冠) of the world's most populous(人口稠密的) country is on China's head for many years. India will take thepositionby 2030. With the population growth rate at 1.58%, India will have more than 1. 53 billion people by the end of 2030.
Now more than 50% of India's population is below the age of 25 and over 65% below the age of 35. About 72.2% of the population lives in some 638, 000villages.
Some of the reasons for India's quickly growing population are poverty, illiteracy(无知)，decrease in death rates and immigration(移民) from Bangladesh and Nepal. India started taking measures to stop the growth rate quite early. India had the “National Family Planning Programme” in 1952. It became the first country in the world to have a population policy. However, it failed to reach the final goal(目标).
