In the United States female crime has grown at a faster rate than male crime over the past couple of decades. Despite this, only limited research has been done by criminologists, psychologists and sociologists on this growing problem. This study examines female criminals; who they are, where they come from, what crimes they commit, why they commit criminal and delinquent acts, and how they are incarcerated. Part One discusses the extent and nature of female crime in the United States, and compares it to male crime. Part Two looks at early theories on the topic. Part Three explores the criminality and deviance of women offenders, while Part Four concentrates on the crimes and delinquency of juveniles. The work concludes with a discussion of female offenders in the custody of correctional authorities.
