The research was intended to determine whether crime and deviance are explained mostly by access to legitimate opportunities. Variables used were median family income; male unemployment; median years of education for males 25 years of age and older; the percentage of families headed by women; and Uniform Crime Rate arrest data for robbery, burglary, and homicide. Results revealed that the measures had different and usually opposite effects on black and white crime rates during the period. In general, the measures of legitimate opportunity had the expected effects on white crime rates, but not on black crime rates. In particular, black crime rates increased with higher family income and educational attainment and decreased as the percentage of female-headed families increased. However, several factors may make the measures of some variables invalid. Other possibilities are that other variables would change the conclusions for black people and that black crime rates during the study period were affected more by perceptions of opportunity than by objective opportunity measures.
