Survey:Annual Population and Social Security Surveys

  • The National Fertility Survey

The National Fertility Survey is conducted every 5 years to investigate the situation and issues regarding marriage, childbirth and child-rearing in Japan. The survey is carried out separately for both married couples and unmarried people. The survey explores policy-related issues from social scientific perspectives. Japan continues to experience a declining fertility, which leads to population decline and population aging as well as changes in people’s lives. Those changes are to influence Japanese society greatly in the future. One of the important themes of the survey is to understand the mechanisms of fertility change and its underlying causes.


  • The National Survey on Migration

Japan has already turned itself into a decreasing population society. However, at the local level such as prefecture, city or municipality, population decline had started evern earlier due to internal migration. Currently, the migration level is relatively stable compared to the rapid economic growth period during the 1970s, but the effect of migration on regional population cannot be ignored. Recently, new migration patterns are observed according to the change of society. The purpose of the survey is to understand the trends and causes of internal migration in Japan and the survey results are reflected to the regional population projection.

  • The National Survey on Social Security and People’s Life

Families and communities serve an important function to supplement the safety net of publicly provided social security. However, the changing family structure and declining economic vitality of individuals and families have transformed this traditional safety net. The purpose of the survey is to discover the status of individuals and households who face economic hardship and to gain knowledge on the capacity of individuals and families to support one another.
