UCR/ Uniform Crime Reporting
The Uniform Crime Reporting Program is a voluntary, nationwide effort of more than 17,000 city, county, and state law enforcement agencies to report data on crimes brought to their agencies attention during a particular calendar year.
In 2003, law enforcement agencies reporting to the UCR Program represented over 93% of the total population of the United States.
The UCR reporting program began in the late 1920s at the suggestion of the International Association of Chiefs of Police (IACP). The Association formed the Committee on Uniform Crime Records and developed a system for collecting and comparing uniform crime statistics among the nations law enforcement agencies.
Seven main offense categories, known as Part I crimes, were chosen to gauge the condition of crime in the United States. These seven offense classes eventually became known as the Crime Index and included both violent and property crimes. The seven original classifications were:
- Forcible Rape
- Aggravated Assault
- Motor Vehicle Theft
Arson was permanently added by congressional mandate in 1982 to coincide with the passage of the Federal “Anti-Arson” act of that year.
The UCR also developed a secondary set of crime classifications known as Part II offenses. This section includes many of the more common crimes which were not contained in the Part I crime categories. Some of the offenses contained in the Part II classification include Assault, Forgery, Fraud, Vandalism, Weapons and Drug offenses, Runaways and Drunkenness. Additionally a category was added for the reporting of “All Other Offenses” not specifically classified in either Part I or Part II.
In the mid-1980’s it was determined by a number of agencies and organizations that additional data was needed to more accurately determine crime trends in the United States. Out of this endeavor the National Incident Based Reporting System or NIBRS was developed.
NIBRS built on the successes of the UCR system and expanded the data collected from just reporting the number of crimes along with the number of arrests or cleared cases to giving a more detailed account of each incident of crime committed. The NIBRS initiative expanded the number of more serious offenses, known as “Group A Offenses” and provided for a more detailed collection of data on both the victims and perpetrators contained in this group. The data collected now identifies such information as the residency status, race, sex and age of both victims and perpetrators of Group A offenses. This allows law enforcement to develop a more comprehensive picture of who the victims are and who is committing the more serious crimes.
NIBRS additionally increased the number of Part II or as NIBRS labels them “Group B” offenses, collecting expanded data on the perpetrators of these crimes.
The Dennis Police Department reports in both UCR and the NIBRS format. The UCR system is that which is displayed in the Annual Town report for ease of comparison from one year to the next.
