Uniform Crime Reporting National Incident Based Reporting System

Statistical data is collected and compiled from 150+ state, county and local law enforcement agencies in New Hampshire for juvenile and adult offense and arrests.

The New Hampshire Uniform Crime Report (UCR) program is a state and national criminal justice data collection program administered by the Federal Bureau of Investigation.  The primary objective of UCR is to collect a reliable set of crime statistics to use in the administration, operation and management of law enforcement agencies. To meet this objective NH collects crime data from 154 state, county, and local law enforcement agencies using the FBI National Incident Based Reporting System (NIBRS) data collection guidelines. Included in the NIBRS data collection are Group "A" offenses, reported as complete incidents including data on victims, offenders, arrestees, circumstances, property, etc.; and Group "B" offenses collect data on arrestees only. Please read additional information on offenses.

NIBRS Website

The State Police Uniform Crime Report Unit (UCR) has partnered with Beyond 20/20 to make the state’s crime statistics available to the public on a new website.  The reports on the website use a variety of measures, i.e. number of incidents, offenses, victims, offenders, etc.) taken from the NIBRS Group A and Group B data submitted by our state, county and local law enforcement agencies.   By clicking on Help – Tutorials you will bring up instructions on creating your own reports.

The public website is now available. Please keep in mind that reports on this website are currently based on a “snapshot” of our database and will not reflect the updates and changes to incident-based records we continue to receive from the contributing agencies.

Caution against Ranking

Every year various state agencies; the media, the public, and other groups, rush to use the reported crime statistics to compile city or county rankings. These rankings do not reflect accurate comparisons as they do not take into account the following variables:

  • Population density and degree of urbanization in each jurisdiction and surrounding area
  • Variations in the composition of the population, particularly youth concentration
  • Population increase due to daily commuters, transients, tourists, shoppers, etc.
  • Modes of transportation and highway systems
  • Cultural conditions
  • Family conditions with respect to divorce and family cohesiveness
  • Climate
  • Effective strength of law enforcement agencies
  • Administrative and investigative emphases of law enforcement

Until data users examine all variables that affect crime in a town, city, or county no meaningful comparisons can be made.  For these reasons the FBI has a long standing policy against ranking cities, counties, states, and universities/colleges on the sole basis of NIBRS crime data.
