For the state itself, the rate of population growth had slowed down – from 17.5% growth in 1991-2001 to 15.7% in 2001-2011.

In terms of absolute population, Bangalore is followed by Belgaum (4.7 million people), Mysore (2.9 mln) and Tumkur (2.6 mln).

Children (those aged 0-6 years) form about 10% of Bangalore’s total population. In Karnataka, total child population is around 11%.
