This paper reports the results of a national survey in which perceptio
ns of environmental health risks were measured for 1275 white and 214
nonwhite persons. The results showed that white women perceived risks
to be much higher than did white men, a result that is consistent with
previous studies. However, this gender difference was not true of non
white women and men, whose perceptions of risk were quite similar. Mos
t striking was the finding that white males tended to differ from ever
yone else in their attitudes and perceptions - on average, they percei
ved risks as much smaller and much more acceptable than did other peop
le. These results suggest that sociopolitical factors such as power, s
tatus, alienation, and trust are strong determiners of people's percep
tion and acceptance of risks.
