Explanatory Notes CPM 101 Annual Report: FY 2011 Police Services / 129 Figure 11 -2 • Some variation in expenditure levels may be due to difference in daytime population levels. Jurisdictions that experience a large influx of commuters, tourists, or other visitors who use police services but who are not counted in the resident population may appear to have disproportionately high expenditure levels on a per capita basis. Figure 11 - 3 • Note that this indicator is calculated on the basis of UCR Part I crimes only. It does not include UCR Part 11 drug violations or other offenses. • The percentage of UCR Part I crimes cleared is calculated by dividing the number of UCR Part I crimes cleared by the number of UCR Part I crimes reported. Among jurisdictions, there is variation in how reported violent crimes are counted. Some jurisdictions do not count unfounded cases as crimes reported; others count unfounded cases because they constitute reports of crimes. The incidence of unfounded reports is unknown. If reports of unfounded crimes are included in the count of crimes reported, the percentage cleared will appear artificially low because it is based on a number higher than the number of actual crimes. • No jurisdictions reported a value of zero. All jurisdictions for which a value is not shown did not report the data or indicated that the data were not available. Figure 11 - 5 • Some variation in the values reported for this indicator may be attributed to differences in state and local blood alcohol thresholds and other standards that may need to be met in order to arrest suspects for driving under the influence (DUI) offenses. Figure 11 - 6 • The way in which calls are received and dispatched can affect response times. For example, in some jurisdictions, top priority police calls are initially received through a local 911 center and then transferred to the police department for dispatch, if necessary. In other jurisdictions, the calls may be both received and dispatched through the 911 center or some other single point of service. In jurisdictions where a transfer is necessary, response times will likely be longer. OICMA Center for Performance Measurement'"
