Predicting symmetry in female/male crime rates

This paper examines changes in female criminality. Data were obtained from 1943 through 1998 on six index crimes: murder, robbery, assault, burglary, auto theft, and larceny. Rape and arson are not included because rape is almost exclusively a male crime, while statistics for arson have not been consistent for the period studied. A review of the literature on female crime is presented. Percentage differences between males and females were obtained for specific crimes for each year. A regression line was computed for this difference by year. Each line is characterized by R2, as a measure of confidence in future predictions and "b" levels to determine slope, and the expected year in which male and female crime will achieve equality if current trends continue. The authors also suggest using the year generated as an index on which to compare growth or decline of female crime. © 2001 Society for Police and Criminal Psychology.
