Longevity indexes LI2 and LI3 (subjects aged 90 and more and 100 and more, respectively, among subjects of 60 and older) were compared in all administrative units on the basis of results of 1989 Census of the population and data of the Central Statistical Office. These values reduce from West to East: LI2 in Western Siberia is equal to 8.48/1000, LI3 to 0.45/1000, in Eastern Siberia these values are 7.48 and 0.35/1000, in the Far East 5.20 and 0.31/1000, in Russia on the whole 9.16 and 0.47/1000, respectively. The territories with relatively high LI2 values were the Aghinsk Buryat Autonomous Territory (11.42/1000), Yakutia (10.79/1000), Altai (9.41/1000).
