The analysis focused on data for 1996-99. Oklahoma’s 1998 incarceration rate of 622 offenders per 100,000 population was the third highest in the country and that its female incarceration rate of 122 was the highest in the country. Drug law offenses were the most common offense among incarcerated; drug possession is the leading offense. Fraud and larceny offenses are the next most common offenses for women, although the numbers convicted for these offenses were much lower. Larceny and drunk-driving offenses are the next most common offenses for men. Arrest rates for women have stayed fairly constant, but incarceration rates for women continue to increase at a faster rate than that for men. Findings suggest that female incarceration may not change in Oklahoma any time soon. Further research should determine the reasons for gender differences among offenders in Oklahoma.
