Vital Statistics by Occupation and Industry: Survey Overview
Overview
Vital Statistics by Occupation and Industry examines the relationship between occupation and industry and births, deaths, stillbirths, marriages, and divorces. It provides basic data for population and health, labour, and welfare policies. After the vital statistics survey began in Meiji 32, it was conducted annually through Showa 42. From Showa 43 onward, occupation and industry were surveyed in Population Census years. Reports have been published every five years since fiscal year Showa 45, and analyses use incidence ratios with the Population Census population by occupation and industry as the denominator.

Overview
The survey covers births, deaths, stillbirths, marriages, and divorces. It aims to clarify their relationship with occupation and industry and provide basic data for population and health, labour, and welfare policies.
After the vital statistics survey began in Meiji 32, it was conducted annually through Showa 42. From Showa 43 onward, occupation and industry were surveyed in Population Census years, and this report has been published every five years since fiscal year Showa 45.
Each event is analyzed by calculating incidence ratios using the Population Census population by occupation and industry as the denominator. For deaths, Occupational and Industrial Mortality Statistics was published twice: for Showa 26–27 and Showa 29–31.
Details
The legal basis includes the Population Dynamics Survey Order and its Enforcement Regulations, rules on stillbirth notifications, ministerial ordinances concerning stillbirth notification forms, and the Family Registration Act and its Enforcement Regulations.
This is a complete enumeration survey, conducted and tabulated by fiscal year from April 1 of a Population Census year through March 31 of the following year. Tabulation was carried out by the Director-General for Policy Planning (Comprehensive Policy and Labour-Management Relations) at the Ministry of Health, Labour and Welfare.
Occupation and industry classifications follow the major categories of the Population Census and describe conditions at the time each event occurred. Rates are calculated using the Japanese population aged 15 and over in the Population Census report, representing occupation and industry as of October 1.
Figures in this fiscal-year survey do not match the calendar-year Vital Statistics. Births and stillborn fetuses classified by the father's occupation are limited to legitimate children.
