India was the first country in the world to launch a national programme for family planning in 1952. However, during the last 11 years, India's population has witnessed the maximum growth when compared to the highly populated nations of the world.
According to a Zee Research Group analysis, in the last eleven years India's population has grown by a maximum growth rate of almost 19%, followed by Brazil (15.38), Indonesia (14.86), US (10.94) and China (5.35).

The World Population day is observed across the globe on July 11, when most of the countries aim to increase the awareness on the various population issues like family planning, maternal health, new born health, sexual and reproductive health.
As per the 2011 report of United Nations Population Fund (UNFPA), an international development agency, it reveals that the 1 billion population mark was reached in 1804 and it took 123 years to cross 2 billion marks in 1927.
However, the rapid growth of the world population started six decades back in 1950. After crossing the two billion mark, population grew to three billion in 1959 and that too in just 32 more years.
Four billion mark was crossed in 1974 and addition of this billion just took 15 years which is half the time taken to reach three from two billion. After another 13 years, population crossed five billion mark in 1987.
Six and seven billion population mark was crossed in year 1999 and 2011 respectively and both these landmarks took additional 12 years to reach over there.
