Adler makes three major assertions about female crime trends: a female crime wave is occurring, the rate increase in female crime is greater than the male increase for almost every major crime, and masculine-feminine boundaries in crime are becoming blurred. Adler bases her contentions on statistics, such as the Uniform Crime Report arrest statistics, and anecdotes, media reports, and some interviews with offenders. Simon, in comparison to Adler, is more rigorous in analyzing statistical data. She finds that significant increases in female crime are relatively restricted, that female violent crime is actually decreasing, but that females are increasingly engaged in white-collar crime. Steffensmeier maintains, however, that this is not true. Females are merely committing more traditionally female crimes. Apparent increases in fraud and embezzlement are only reflecting changes in participation in shoplifting and writing bad checks. Regardless of the conflicts among these theories, several tenets can guide future research: (1) occupational gains by women have been highly limited; (2) reliance upon Uniform Crime Reports arrest statistics as a basic data source may result in failure to understand female crime trends; and (3) most trend research (except for Steffensmeier's) totally ignores the differential impact of the women's movement on different segments of the population. Discussion of the methodology used by the three researchers are included. Thirty-three references are provided.
