In order to obtain fundamental data to set up safety countermeasures against stair accidents, fatal falls on stairs during a 40 years period from 1950 to 1989 were analyzed from mortality statistics. Raw coding data of 1278 deaths originating from death certificates over a 2 years period from 1979 to 1980 in Japan were also analyzed. From obtained results in this study, most victims received injuries on their heads. Ageing was considered to be one of the major factors causing fatal falls, and especially for males drinking habits also were influencing factors to cause fatal falls. Exponential relations between fatality rates and ages could be found in female trends.
