• 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

The National Survey on Social Security and People's Life aims to aid in deciphering how individuals interact with social security systems. The study gauges how people live their lives, connect with their family and community, and how those connections provide support. The data is invaluable for future local and national governments creating effective social security policies.
The survey itself is conducted in two parts: a household survey and an individual survey. Only one household survey is to be completed per household whereas the individual survey is to be completed by each household member 18 or older. Of the many survey themes there are questions investigating family relationships, socioeconomic status, public and private support systems, poverty and deprivation, individual's levels of self-reliance, social isolation, as well as basic demographic data. This information is collected in order to thoroughly examine and improve current social security systems.
