Statistics released by the Union ministry of health and family welfare show that life expectancy in India has gone up by five years, from 62.3 years for males and 63.9 years for females in 2001-2005 to 67.3 years and 69.6 years respectively in 2011-2015. Experts attribute this jump - higher than that in the previous decade - to better immunization and nutrition, coupled with prevention and treatment of infectious diseases.
The World Health Organization (WHO) defines life expectancy as "the average number of years a person is expected to live on the basis of the current mortality rates and prevalence distribution of health states in a population". In India, average life expectancy which used to be around 42 in 1960,steadily climbed to around 48 in 1980, 58.5 in 1990 and around 1962's in 2000.
