The Merseyside police received just under 20,000 calls to domestic disputes in each of the 3 years. Calls to domestic disputes had a predictable seasonal variation of 25-30 percent; peaks occurred at the end of December and beginning of January and from mid-July to mid-August. Calls regarding burglary declined during each year studied, but had a predictable seasonal variation of 35-40 percent. The low point occurred in July or August, the highest levels occurred during February and March. Such patterns did not exist for vehicle crime, for which a rapid decline occurred in one year. Findings suggest that the seasonal patterns could provide insight into the problems involved, as well as direction for crime prevention activity. Tables, footnotes, appended tables, and 17 references
