Abstract
A database of casualties requiring at least a four-day absence due to occupational accidents was opened to the public via the website of the Ministry of Health, Labour and Welfare in Japan. The number of records from 2006 to 2010 is over 150,000. Each instance includes information such as the type of industry, cause, kind of accident, and the age of the dead or the injured worker. In this report, histograms are shown of accidents for each type of industry, cause, and kind of accident by age at one or two-year intervals. The histogram patterns indicate individual properties. Each histogram is a faithful representation of the workers’ accidents and should be helpful in discussing more effective safety measures, especially for elderly workers. We forecast the number of casualties in construction work within the near future as an example application of the age distribution of casualties.
