Population of Tamilnadu in 2011 of 72.1 million accounts for about 5.9% of India’s population of 1210 million. Tamilnadu is the 7th largest state in the country behind UP, Bihar, West Bengal, Madhya Pradesh,Maharashtra and Andhra Pradesh. However, the population of children of Tamilnadu of 0-6 years, is only 6.89 million which works out to only 4.3% of the total child population of 158.7 million. It ranks 9th largest behind Rajasthan, UP, Bihar, West Bengal, Madhya Pradesh, Gujarat, Maharashtra and Andhra Pradesh. In the normal course, Tamilnadu’s population in India’s population would also in future come to around 4.4%. But this level of population will not be able to maintain the fairly large industry, agriculture and service sector in the state. There will naturally be migration from densly populated states like Bihar, UP, West Bengal and low income states like Orissa. To sustain the industry, agriculture and service sector development, the state should devise ways and means to permanently absorb the population from other states by creating necessary conditions like extending education in mother tongue to the migrant children, providing all facilities and concessions to them as are being given to local population like free rations, clothing, house sites, houses etc.
