Criminal justice system policy makers have recently begun to utilize sophisticated techniques of analysis to explore questions of resource allocation and program evaluation.1, 2, 6, 8, 10 All too often, however, the benefits of such techniques have been denied to the large proportion of criminal justice units which lack access to extensive computer facilities and large technical staffs. This paper illustrates how one important crime data time series property-seasonal variation- may be adjusted for and utilized with some fairly simple procedures. The police operations and planning implications of the presence of seasonality in crime data are then examined. The authors develop their discussion with reference to seasonal variation in monthly data on major crimes for a large United States urban area, Miami, Florida. The time period of the study is 1949-1972.
