This document analyzes India's population data from 1901 to 2011. It shows that the population has steadily increased each decade, growing from 238 million in 1901 to over 1.2 billion in 2011. The growth rate peaked in the 1980s at over 2% per decade due to declining death rates and steady birth rates.
