title: [Re-estimation of the population by age and sex and vital rates in postwar Japan].
abstract: "In this study Japanese population by age and sex was re-estimated for the postwar years and both fertility and mortality rates were also re-estimated based on these revised populations."  Using the cohort component method, the authors analyze data from seven censuses conducted between 1950 and 1980, adjusting for international migration.  The revised population figures are then used to re-estimate age- and sex-specific death probabilities and to derive life table functions for the postwar years.  Problems with the reliability of the census data are emphasized, in particular the under-enumeration of the total population and of specific subgroups, and the bias in offical birthrate estimates arising from the procedure for estimating mid-year populations.
