Preliminary Semiannual Uniform Crime Report, January-June, 2011
Preliminary figures indicate that, as a whole, law enforcement agencies throughout the Nation reported a decrease of 6.4 percent in the number of violent crimes brought to their attention for the first 6 months of 2011 when compared with figures reported for the same time in 2010. The violent crime category includes murder, forcible rape, robbery, and aggravated assault. The number of property crimes in the United States from January to June of 2011 decreased 3.7 percent when compared with data from the same time period in 2010. Property crimes include burglary, larceny-theft, and motor vehicle theft. Arson is also a property crime, but data for arson are not included in property crime totals. Figures for 2011 indicate that arson decreased 8.6 percent when compared to 2010 figures from the same time period.
The data presented in Tables 1 and 2 indicate the percent change in offenses known to law enforcement for the first 6 months of 2011 compared to those for the first half of 2010 by population group and region, respectively. Table 3 reflects the percent change in offenses reported within the Nation for consecutive years (each year compared to the prior year). Table 4 presents the number of offenses known to law enforcement for agencies with a resident population of 100,000 and over and that provided 6 months of complete data for 2011. In addition, Table 4 presents 6 months of 2010 data, where available, as a point of comparison. All data in this Report are preliminary.
Figures used in this Report were submitted voluntarily by law enforcement agencies throughout the country. Individuals using these tabulations are cautioned against drawing conclusions by making direct comparisons between cities. Comparisons lead to simplistic and/or incomplete analyses that often create misleading perceptions adversely affecting communities and their residents. Valid assessments are possible only with careful study and analysis of the range of unique conditions affecting each local law enforcement jurisdiction. It is important to remember that crime is a social problem and, therefore, a concern of the entire community. The efforts of law enforcement are limited to factors within its control. The data user is, therefore, cautioned against comparing statistical data of individual agencies.
