CRIME IN COLORADO - 1999
This annual report represents data on crime and arrests reported by law enforcement agencies through the Colorado Uniform Crime Reporting Program (UCR). During 1999, 238 law enforcement agencies were responsible for reporting crimes and arrests to the Colorado Bureau of Investigation (CBI). Law enforcement includes sheriffs, police, and state agencies. One hundred forty four (144) law enforcement agencies reported incident based statistics, 76 agencies reported summary based statistics, and 18 agencies did not report statistics to the CBI in 1999. Both the incident based and summary based statistics are collected and stored in the Colorado Crime Information Center (CCIC) computer at the Colorado Bureau of Investigation.
The National UCR Program - Historical Background*
In the 1920s,
the International Association of Chiefs of Police (IACP), recognizing a need for national
crime statistics, formed the Committee on Uniform Crime Records in order to develop a
system of uniform police statistics. The committee determined the most appropriate tool in
which to record crime statistics was to base the measurements on established criminal
offenses already known to law enforcement. Accordingly, the committee evaluated various
crimes on the basis of their seriousness, frequency of occurrence, pervasiveness in all
geographic areas and the likelihood of the offense being reported to law enforcement.
After studying the state criminal codes and making an evaluation of the record keeping
practices in use, the committee completed a plan in 1929 for crime reporting which became
the foundation of the National Uniform Crime Reporting Program.

National Incident Based Reporting (NIBRS)
NIBRS is an incident based reporting system. Data is reported on each single crime occurrence. NIBRS was designed to be a by-product of local, state and federal automated records systems. The NIBRS program collects data on each single incident and arrest within 22 primary offense categories, referred to as Group A Offenses, and arrest data only on 11 additional offenses which are referred to as Group B Offenses. For each offense known to police within the Group A category, incident, victim, property, offender, and arrestee information is gathered. The collection of the expanded crime data in NIBRS allows law enforcement, legislators, planners and administrators and the general public to better assess the nature and extent of crime. Full participation in the NIBRS program allows law enforcement agencies to have a common denominator in linking with other law enforcement agencies, providing extensive, specific crime information concerning similar jurisdictions, which can further assist in the identification of common crime problems or trends. NIBRS data has the capability of furnishing information on a multitude of offenses including weapon violations, drug/narcotic offenses, hate crimes, domestic violence, abuse of the elderly, gang related crimes, and alcohol or drug related crimes. The FBI began accepting NIBRS data in January of 1989. Colorado is among 18 states which have been certified for submission of NIBRS data to the FBI.
The Colorado UCR Program
The Colorado Uniform
Crime Reporting Program was developed to depict an accurate picture of crimes reported to
local law enforcement agencies across the state. The program was designed in 1975 to be an
integral part of the Colorado Computerized Criminal Justice Information system (CCIC) and
is administered by the CBI. The program began in January 1976 with the collection of
monthly UCR summary data from participating law enforcement agencies. Colorado Revised
Statutes mandate the submission of uniform crime data to the CBI.
