[JURIST] The FBI [official website] on Tuesday released preliminary crime statistics [report; press release] indicating declines in reported violent crimes and property crimes in the US. The statistics are based upon data collected during the first six months of 2013 submitted by nearly 13,000 federal and state law enforcement agencies around the nation. According to the FBI, the numbers indicate that murders declined 6.9 percent, forcible rapes declined 10.6 percent, aggravated assaults decreased 6.6 percent and robbery offenses decreased 1.8 percent from 2012. In addition the data reportedly indicates that burglary offenses decreased 8.1 percent, larceny-theft offenses decreased 4.7 percent and motor vehicle thefts decreased by 3.2 percent from 2012. While authorities have reportedly attributed the reductions to more effective law enforcement [NYT report], the FBI urges those using the data to account for various factors:
Individuals using these [crime] 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.Reports indicate that the FBI's data continues a 25-year decline in violent crime and property crime within the US.
