Stairs are among the most hazardous features of the everyday environment, yet stairway falls have received little research attention. A stratified random sample of Austrian residents was surveyed in person in 1989. Of over 55,000 respondents, 147 reported a stairway injury in the previous year that limited activity for at least one day. Thirty-seven percent of these injuries resulted in hospitalization. Extrapolating to the entire country of 8 million people, each year some 20,000 Austrians sustain serious stairway injuries resulting in over 7,500 hospitalizations. The incidence of stairway injury increases monotonically with age, and females are more at risk than males. The stereotypical stairway injury victim is an elderly woman, not highly educated, who is unmarried and living alone.
