Age demographics to dependency ratio, on this World Population Day lets have a glance of India versus World population
For the first time since independence, the absolute increase in population is more in urban areas than in rural areas. The level of urbanisation has increased from 27.81 per cent in the 2001 Census to 31.16 per cent in the 2011 Census. While the proportion of rural population declined from 72.19 per cent to 68.84 per cent. Reason behind them is increasing prosperity, jobs, and a surge in migration from villages and towns to cities for the same.
Child population in India has decreased where as overall population has increased about 17.64% in last 10 years. Something that is alarming is the sex ratio of children under 6 years of has dropped to just 914 girl child per 1000 boys. Both rural and urban India has the same negative change.
The age structure of a population affects a nation's key socioeconomic issues. Countries with young populations (under age 15) need to invest more in schools. Here, the decline in the age group (0-14 years) is because of increase 41% of the young population which falls under less than 18 years of age.
The number of Indians over the age of 60 has hit an all-time high, accounting for 8.6 per cent of the country?s 121-crore population. An ageing society could have implications for any government in terms of higher spending on medical or healthcare and on pensions. As per the United Nations Population Fund (UNFPA) and HelpAge International-- 80 percent of world?s older people will live in developing countries by 2050.
