The actual growth rate of population is not uniform in all parts of the country. The rate is higher in some parts than in others. The average decadal growth in the country was 21.39% during 1991-2001.
If we look at inter-state differences, then it has been observed that Kerala has the lowest growth rate i.e. 9.42%, whereas the state of Nagaland has the highest growth rate of 64.41%.
The broad state level pattern which emerges reflect that there is a clear cut north-south divide. All the northern and north eastern states have recorded high growth rates whereas all the southern states have low growth rates. This is mainly due to differences in the level of socio-economic development which include high literacy rates, better primary health care facilities, more urban population, more development economy, etc.
