Patna, Jul 30: The urban population in Bihar has increased to 11.30 per cent of the estimated total population of 10.38 crore in the state but the sex ratio has dropped to 916 females per 1000 males in the past decade.

There was a corresponding decline in rural population. In 2011 88.78 per cent of the total population was from rural areas, while in 2001 it was 89.50 per cent.

The decadal growth of population was 25.07 per cent. The provisional data, earlier released by the directorate, showed a 20 per cent rise in the state's female literacy rate from 33.12 per cent in 2001 to 53.33 per cent this year.

The sex ratio dropped to 916 females per 1,000 males this year from 919 in 2001, with a sharp fall in the child population (aged 0-6 years) from 942 girl children in 2001 to 933 now.
