"This paper proposes to construct, for India, a two-regional life table, considering two regions viz., rural and urban. Such a table provides information on the probabilities of survivorship and migration, as well as life expectancy by age, region and place of birth and in particular information on: (1) The probability that an individual living in a rural area at age x will be living in an urban area at age y. (2) Life expectancy at birth in a rural area, and the number of years on average this individual may live in an urban area.  The aim here is to compare and contrast rural to urban and urban to rural migration probabilities by sex and age for the years 1971, 1981 and 1991, and provide the underlying reasons. Region-specific life expectancy is also compared for these years." (SUMMARY IN ITA AND FRE)
