Population Projection
In order to provide basic information for planning mid- to long-term national social security system and for other related policies, the National Institute of Population and Social Security Research releases various projections regarding population and social security. They include “Population Projections for Japan,” “Population Projections by Prefecture,” “Population Projections by Municipality,” Household Projections for Japan,” and “Household Projections by Prefecture.”
Population Projection for Japan
“Population Projection for Japan” is a projection of the overall size and the age-sex breakdown of the future population in Japan, used widely as an important reference by the national and local governments and in other various fields. This projection is based on information from the Census, vital statistics, as well as research developed from various national representative surveys on population and social security problems conducted as the Institute.

Regional Population Projections
Due to declining fertility rates and the ageing of the population, demand for regional population projections (by prefecture and by municipality) as the basis of various economic, social and welfare programs have been significantly increasing. According to our regional population projections, the pressure of population decline will grow constantly in all regions, although there are considerable regional variations.
●Regional Population Projection:
 Population increase of residents 65 years and older by prefecture from 2010 to 2040
