Outline of the System of Social and Demographic Statistics of Japan

1. The System of Social and Demographic Statistics of Japan

The System of Social and Demographic Statistics of Japan is a system in which statistical data in a wide range of fields are collected, normalised and organised. The system describes the lives of Japanese people in various fields. The purpose of the system is to provide basic data useful for various kinds of administrative programmes, policy-making and analysis of regional differences. It was started by the Statistics Bureau in fiscal 1976.

What is characteristic of the system is that the data are organised for each of prefectures (To, Do, Fu and Ken) and municipalities (Shi, Ku, Machi and Mura), thus enabling regional comparison and analysis.

2. Basic Data collected in the System

In the system, basic data are collected in 13 fields from "A. Population and Households" to "M.Daily Time". The number of basic data items is about 2,910 for prefectures, about 750 for Shi and Ku, and about 730 for Machi and Mura respectively (as of Fiscal Year 2016).

3. Compilation of the System

The system is compiled by the following process:

(1) Determination of basic data to be collected
(2) Collection of basic data
      - Statistical Data quoted from report books and computer readable media
      - Business Data from organisations
(3) Input and evaluation of basic data
(4) Systematisation of basic data and indicator calculation
