This annual report
represents data on crime and arrests reported by law enforcement agencies
through the Colorado Uniform Crime Reporting Program (UCR). During 2000,
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. Colorado law enforcement
agencies report both incident based and summary based statistics which
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
Seven offenses were
chosen as an index for gauging fluctuations in the overall volume and
rate of crime. These offenses were known collectively as the Crime Index
and were divided into two categories. The first category was for violent
crimes, including murder and non-negligent manslaughter, forcible rape,
robbery, and aggravated assault. The second category included burglary,
larceny/theft, and motor vehicle theft. By congressional mandate, the
offense of arson was added as an eighth index offense in 1979. The reporting
of this data is commonly referred to as summary or hierarchy reporting.
In summary reporting only the total number of crimes and arrests are
During the early
planning of the UCR program, it was recognized that the differences
among criminal codes prohibited a simple totaling of individual state
statistics to arrive at a national total. In addition, because of the
variances in punishment, no distinction between felony and misdemeanor
crimes could be made. Therefore, to avoid these problems and to provide
nationwide uniformity in crime reporting, nationally standardized offense
definitions were formulated for law enforcement agencies to use when
submitting crime data.
In the 1930s,
the FBI was designated to serve as the national clearing house for the
crime data collected. In 1966, the National Sheriffs Association
established a committee and began to encourage sheriffs throughout the
country to participate fully in the UCR Program. Throughout the first
60 years of operation, the UCR Program remained virtually unchanged
in terms of the data collected and disseminated. In the late 1970s,
the law enforcement community requested a thorough evaluation of the
UCR Program with the objective of recommending an expanded and enhanced
program to meet law enforcement needs in the 21st century. Following
a multi-year study, a "Blueprint for the Future of the Uniform
Crime Reporting Program" was developed. Using the "Blueprint"
and in consultation with local and state law enforcement executives,
new guidelines for Uniform Crime Report were formulated and the National
Incident Based Reporting System was developed.
in the U.S., FBI, Washington D.C.
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.
The Colorado UCR
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.
It is the responsibility
of the CBI to collect and verify the statistical data submitted by local
law enforcement agencies and to publish the annual Crime in Colorado
publication. The CBI also sends all error free statistical crime data
to the FBI. Colorados incident crime reporting system began in
1975 and was designed consistent with advice from the CCIC Board of
Executive Directors. The Board is comprised of sheriffs, chiefs of police,
and state level criminal justice administrators. In 1994, the CBI adopted
the national incident based standards.
The FBI certified
the CBI for NIBRS data submission in 1997. This allows the CBI to report
NIBRS statistical data to the FBI via computer tapes for all local law
enforcement agencies providing error free data.
The CBI NIBRS staff
is grateful to the many Colorado sheriffs, chiefs and state agency heads
who have devoted considerable portions of their resources to Uniform
Crime Reporting and in particular to those agencies pioneering incident
based reporting in Colorado.
