Based on the latest results from the Population Census of Japan and the Vital Statistics of Japan,
the National Institute of Population and Social Security Research in Japan (IPSS) has conducted a new national population projection exercise
(Population Projections for Japan: 2016 to 2065).
This is the 15th release of national population projections by the Institute, including the period before the integration between the Institute of Population Problems and the Social Development Research Institute.

A. The Results of Projections According to the Three Fertility Variants with Medium-Mortality Assumption
B. The Results of Projections According to the Medium-Fertility Assumption with High- and Low-Mortality Assumptions
We made auxiliary projections for the period from 2061 to 2110, which may be used as a reference for analysis of long-term population projections. In these projections, the survival rate-fertility rate, sex ratio at birth, and international migration rate are assumed to remain constant from 2061.
Conditional projections are quantitative simulations for analyzing the responses on the future populations to the changes of the assumptions in mechanical manners. The results of the counterfactual simulations of the future population corresponding to various scenarios with different fertility and non-Japanese net migration levels are exhibited.
