=== Crime statistics ===
During the 1920s the FBI began issuing crime reports by gathering numbers from local police departments.<ref name="'70s">{{cite book |title=How We Got Here: The '70s |last=Frum |first=David |author-link=David Frum |year=2000 |publisher=Basic Books |location=New York, NY |isbn=0-465-04195-7 |page=[https://archive.org/details/howwegothere70sd00frum/page/12 12] |url=https://archive.org/details/howwegothere70sd00frum/page/12}}</ref> Due to limitations of this system that were discovered during the 1960s and 1970s—victims often simply did not report crimes to the police in the first place—the [[United States Department of Justice|Department of Justice]] developed an alternative method of tallying crime, the victimization survey.<ref name="'70s" />

==== Uniform Crime Reports ====
{{Main|Uniform Crime Reports}}
The Uniform Crime Reports (UCR) compile data from over 17,000 law enforcement agencies across the country. They provide detailed data regarding the volume of crimes to include arrest, clearance (or closing a case), and law enforcement officer information. The UCR focuses its data collection on violent crimes, hate crimes, and property crimes.<ref name="pubs" /> Created in the 1920s, the UCR system has not proven to be as ''uniform'' as its name implies. The UCR data only reflect the most serious offense in the case of connected crimes and has a very restrictive definition of rape. Since about 93% of the data submitted to the FBI is in this format, the UCR stands out as the publication of choice as most states require law enforcement agencies to submit this data.

Preliminary Annual ''Uniform Crime Report'' for 2006 was released on June 4, 2006. The report shows violent crime offenses rose 1.3%, but the number of property crime offenses decreased 2.9% compared to 2005.<ref name="publications_ucr2006">{{cite web |url=https://www.fbi.gov/ucr/06prelim/index.html |title=Preliminary Crime Statistics for 2006 |publisher=Federal Bureau of Investigation |archive-url=https://web.archive.org/web/20100411123900/http://www.fbi.gov/ucr/06prelim/index.html |archive-date=April 11, 2010}}</ref>

==== National Incident-Based Reporting System ====
{{Main|National Incident-Based Reporting System}}
The National Incident-Based Reporting System (NIBRS) [[crime statistics]] system aims to address limitations inherent in UCR data. The system is used by law enforcement agencies in the United States for collecting and reporting data on crimes. Local, state, and federal agencies generate NIBRS data from their records management systems. Data is collected on every incident and arrest in the Group A offense category. The Group A offenses are 46 specific crimes grouped in 22 offense categories. Specific facts about these offenses are gathered and reported in the NIBRS system. In addition to the Group A offenses, eleven Group B offenses are reported with only the arrest information. The NIBRS system is in greater detail than the summary-based UCR system. {{as of|2004|df=US}}, 5,271 law enforcement agencies submitted NIBRS data. That amount represents 20% of the United States population and 16% of the crime statistics data collected by the FBI.
