title: [On measuring instability in demography].
abstract: "A concept of instability as an integral measure for estimating [the] age structure of real and stable populations is substantiated.  A system of instability indices is suggested [that] permits estimating the effect of external conditions and internal factors of population reproduction on the age structure."  The geographical focus is on the USSR. (SUMMARY IN ENG)
