Little is currently known about differences in the sex offenses of blacks and whites ii the 1nited states. Many major studies of sexual behavior and of sex offenders have purposely excluded data on blacks. This paper presents comparative data on 47 black and 47 white sex offenders in terms of the nature of the offense and victim characteristics. It was found that black offenders weremore likely than white offenders to engage invaginal intercourse with their victims, showed a trend to use force in their offenses, and were more likely to select adult female victims. These differences, however, appear to be due primarily to class rather than racial differences. Limitations of these dataare discussed.
