Race Differences in Sexual Behavior and Their Demographic Implications

Differences between blacks and whites in sexual behavior posited in Rushton's theory of r-K race differences were examined in the United States in an analysis of the annual surveys of the National Opinion Research Center for 1990–1996. This data set was analysed for black-white differences in numbers of sexual partners during the last 5 years and for frequency of sexual intercourse. The general pattern of the results was for blacks to report more sexual partners than whites and for black males to report greater frequency of sexual intercourse, consistent with Rushton's theory. This result has implications for the control of the AIDS epidemic and for the demographic transition among blacks.
