Variance components analysis was used to investigate the relative contribution of local, State, and national forces on variance in Part I crime rates between 1967 and 1980.
Abstract
The initial sample consisted of 581 jurisdictions for which Uniform Crime Report Data were available for the period under study. A sample of up to 20 jurisdictions with a population of 10,000 or more in 1967 was randomly selected from each State. Results indicate that national-level forces accounted for over 50 percent of the combined cross-sectional and temporal variation in total Part I crime rates, while the influence of State-level forces was not very large. In addition, different crimes showed different patterns of influence. Methodological and policy implications of these findings are discussed. Tabular data and 13 references.
