FBI releases 2011 crime statistics


According to the figures released today by the FBI, the estimated number of violent crimes in 2011 declined for the fifth consecutive year.
Property crimes also decreased, marking the ninth straight year that the collective estimates for these offenses declined.
The 2011 statistics show that the estimated volumes of violent and property crimes declined 3.8 percent and 0.5 percent, respectively, when compared with the 2010 estimates. The violent crime rate for the year was 386.3 offenses per 100,000 inhabitants (a 4.5 percent decrease from the 2010 rate), and the property crime rate was 2,908.7 offenses per 100,000 persons (a 1.3 percent decrease from the 2010 figure).
These and additional data are presented in the 2011 edition of the FBI’s annual report Crime in the United States. This publication is a statistical compilation of offense and arrest data reported by law enforcement agencies voluntarily participating in the FBI’s Uniform Crime Reporting (UCR) Program.
The UCR Program collects information on crimes reported by law enforcement agencies regarding the violent crimes of murder and nonnegligent manslaughter, forcible rape, robbery, and aggravated assault, as well as the property crimes of burglary, larceny-theft, motor vehicle theft, and arson. (Although the FBI classifies arson as a property crime, it does not estimate arson data because of variations in the level of participation by the reporting agencies. Consequently, arson is not included in the property crime estimate.) The program also collects arrest data for the offenses listed above plus 20 additional offenses that include all other crimes except traffic violations.
In 2011, there were 18,233 city, county, university and college, state, tribal, and federal agencies that participated in the UCR Program. A summary of the statistics reported by these agencies, which are included in Crime in the United States, 2011, follows:
  • Nationwide in 2011, there were an estimated 1,203,564 violent crimes.
  • Each of the four violent crime offense estimates decreased when compared with the 2010 estimates. Robbery had the largest decrease at 4.0 percent, followed by aggravated assault with a 3.9 percent decline, forcible rape with a 2.5 percent decline, and murder and nonnegligent manslaughter with a 0.7 percent decrease.
  • Nationwide in 2011, there were an estimated 9,063,173 property crimes.
  • There was a 3.3 percent decline in motor vehicle theft and a 0.7 percent decline in larceny-theft offenses. Estimated burglary offenses increased by 0.9 percent when compared with the 2010 estimate.
  • Collectively, victims of property crimes (excluding arson) lost an estimated $15.6 billion in 2011.
  • The FBI estimated that in 2011, agencies nationwide made about 12.4 million arrests, excluding traffic violations.
  • The 2011 arrest rate for violent crimes was 172.3 per 100,000 inhabitants; for property crime, the rate was 531.3 per 100,000 inhabitants.
  • By violent crime offense, the arrest rate for murder and nonnegligent manslaughter was 3.5; forcible rape, 6.3; robbery, 34.5; and aggravated assault was 128.0 arrests per 100,000 inhabitants.
  • By property crime offense, the arrest rate for burglary was 95.6; larceny-theft, 410.6; and motor vehicle theft, 21.4 per 100,000 inhabitants. The arrest rate for arson was 3.8 per 100,000 inhabitants.
  • In 2011, there were 14,633 law enforcement agencies that reported their staffing levels to the FBI. These agencies reported that, as of October 31, 2011, they collectively employed 698,460 sworn officers and 303,524 civilians, a rate of 3.4 employees for each 1,000 inhabitants.
Caution against ranking: Each year when Crime in the United States is published, some entities use the figures to compile rankings of cities and counties. These rough rankings provide no insight into the numerous variables that mold crime in a particular town, city, county, state, tribal area, or region. Consequently, they 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. The data user is, therefore, cautioned against comparing statistical data of individual reporting units from cities, metropolitan areas, states, or colleges or universities solely on the basis of their population coverage or student enrollment.
