Japan? Population Estimates released
In April 2009, the Statistics Bureau of Japan (SBJ) released the Current Population Estimates (annual report)1*) as of October 1, 2008.
Note: 1*) The SBJ publishes two kinds of reports on Current Population Estimates: Annual report on estimates as of October 1 and Monthly report on estimates as of the first day of each month. The annual report includes more detail information ("population by age (single year) and sex for Japan" and "population by age (5-year age group) and sex for prefectures") compared with the monthly report which consists of "population by age (single year) and sex for Japan" only.
Statistics on Japan? population is obtained in detail from the Population Census conducted by the SBJ every five years. Furthermore, during the inter-census period, the SBJ has been compiling the Current Population Estimates, based on the latest census population data, and extrapolated from there using Natural Change (Live births, Deaths) and Migration Change (immigration, emigration) derived from the Vital Statistics (Ministry of Health, Labour and Welfare) and the Statistical Survey on Legal Migrants (Ministry of Justice), etc.
The summary of the estimates as of October 1, 2008 is as follows.
