• According to the Census 2011 provisional reports, India's population in 2011 was 1,210,854,977 (1.21 billion), compared to 1,028,610,328 in 2001. The population increase is:
○ 1,210,854,977 − 1,028,610,328 = 182,244,649 (approximately 182.2 million).
○ This is more than 181 million.
• Decadal Growth Rate (2001 - 2011): The Census 2011 reports a decadal growth rate of 17.64% (or 17.7% in some sources), compared to 21.54% in 1991 - 2001. The decline is:
○ 21.54% − 17.64% = 3.90 percentage points
• Post-Independence decadal growth rates (from Census data):
○ 1941 - 1951: 13.31%
○ 1951 - 1961: 21.51%
○ 1961 - 1971: 24.80%
○ 1971 - 1981: 24.66%
○ 1981 - 1991: 23.87%
○ 1991 - 2001: 21.54%
○ 2001 - 2011: 17.64%
• The 3.90% decline from 1991 - 2001 to 2001 - 2011 is the largest drop in decadal growth rate since Independence, surpassing previous declines (e.g., −2.33% from 1981 - 1991 to 1991 - 2001).
