Uniform Crime Reports & Online Crime Mapping
As a service to the public, JSO provides crime incident information with a mapping program. With prompting from the user, the information provided will show the number of police reports written for selected crimes, within a selected geographical area, or specific address or location. The type of crime and number of offenses will be presented in a table format, with insightful demographic information, such as the time of day the crime occurred. This information is not intended to serve as official crime data.

Jacksonville Uniform Crime Reports (UCR) Statistics
"The Uniform Crime Reporting (UCR) Program is a nationwide, cooperative statistical effort of more than 17,000 city, university and college, county, state, tribal, and federal law enforcement agencies voluntarily reporting data on crimes brought to their attention. Since 1930, the FBI has administered the UCR Program and continued to assess and monitor the nature and type of crime in the Nation. The Program's primary objective is to generate reliable information for use in law enforcement administration, operation, and management; however, its data have over the years become one of the country's leading social indicators. Criminologists, sociologists, legislators, municipal planners, the media, and other students of criminal justice use the data for varied research and planning purposes."
Get the Statistics:
Go to http://www.fdle.state.fl.us/fsac/ucr/ for the Official Annual and Semi-Annual Uniform Crime statistics for Jacksonville and all cities and counties in Florida.
Official Annual Uniform Crime statistics for all reporting cities nationally will also be located at the Federal Bureau of Investigations UCR link at http://www.fbi.gov/ucr/ucr.htm
The above links are the only official UCR sites to obtain UCR guidelines or statistics for the City of Jacksonville or Duval County (other city and county UCR data is available as well).
Historical background of UCR
"Recognizing a need for national crime statistics, the IACP formed the Committee on Uniform Crime Records in the 1920s to develop a system of uniform crime statistics. After studying state criminal codes and making an evaluation of the recordkeeping practices in use, the Committee completed a plan for crime reporting that became the foundation of the UCR Program in 1929. The plan included standardized offense definitions for seven main offense classifications known as Part I crimes to gauge fluctuations in the overall volume and rate of crime. Developers also instituted the Hierarchy Rule as the main reporting procedure for what is now known as the Summary reporting system of UCR.
The seven Part I offense classifications included the violent crimes of Murder and non-negligent manslaughter, forcible rape, robbery, aggravated assault, and the property crimes of burglary, larceny-theft, and motor vehicle theft. By congressional mandate, arson was added as the eighth Part I offense category in 1979. (Does not include all crimes in a jurisdiction only those defined above)
In January 1930, 400 cities representing 20 million inhabitants in 43 states began participating in the UCR Program. Congress enacted Title 28, Section 534, of the United States Code authorizing the Attorney General to gather crime information that same year. The Attorney General, in turn, designated the FBI to serve as the national clearinghouse for the crime data collected. Every year since, data based on uniform classifications and procedures for reporting offenses and arrests have been obtained from the Nation's law enforcement agencies.
Cautions against Rankings:
Variables Affecting Crime
"Each year when Crime in the United States is published, many entities—news media, tourism agencies, and other groups with an interest in crime in our Nation—use reported figures to compile rankings of cities and counties. These rankings, however, are merely a quick choice made by the data user; they provide no insight into the many variables that mold the crime in a particular town, city, county, state, region, or other jurisdiction. Consequently, these rankings lead to simplistic and/or incomplete analyses that often create misleading perceptions adversely affecting cities and counties, along with their residents."
Consider other Characteristics of a Jurisdiction
"To assess criminality and law enforcement's response from jurisdiction to jurisdiction, one must consider many variables, some of which, while having significant impact on crime, are not readily measurable or applicable pervasively among all locales. Geographic and demographic factors specific to each jurisdiction must be considered and applied if one is going to make an accurate and complete assessment of crime in that jurisdiction. Several sources of information are available that may assist the responsible researcher in exploring the many variables that affect crime in a particular locale. The U.S. Census Bureau data, for example, can be used to better understand the makeup of a locale's population. The transience of the population, its racial and ethnic makeup, its composition by age and gender, educational levels, and prevalent family structures are all key factors in assessing and comprehending the crime issue.
Local chambers of commerce, government agencies, planning offices, or similar entities provide information regarding the economic and cultural makeup of cities and counties. Understanding a jurisdiction's industrial/economic base; its dependence upon neighboring jurisdictions; its transportation system; its economic dependence on nonresidents (such as tourists and convention attendees); its proximity to military installations, correctional facilities, etc., all contribute to accurately gauging and interpreting the crime known to and reported by law enforcement.
The strength (personnel and other resources) and the aggressiveness of a jurisdiction's law enforcement agency are also key factors in understanding the nature and extent of crime occurring in that area. Although information pertaining to the number of sworn and civilian employees can be found in this publication, it cannot be used alone as an assessment of the emphasis that a community places on enforcing the law. For example, one city may report more crime than a comparable one, not because there is more crime, but rather because its law enforcement agency through proactive efforts identifies more offenses. Attitudes of the citizens toward crime and their crime reporting practices, especially concerning minor offenses, also have an impact of the volume of crimes known to police."
Make valid assessments of crime
"It is incumbent upon all data users to become as well educated as possible about how to understand and quantify the nature and extent of crime in the United States and in any of the more than 17,000 jurisdictions represented by law enforcement contributors to the Uniform Crime Reporting (UCR) Program. Valid assessments are possible only with careful study and analysis of the various unique conditions affecting each local law enforcement jurisdiction.
Historically, the causes and origins of crime have been the subjects of investigation by many disciplines. Some factors that are known to affect the volume and type of crime occurring from place to place are:
- Population density and degree of urbanization.
- Variations in composition of the population, particularly youth concentration.
- Stability of the population with respect to residents' mobility, commuting patterns, and transient factors.
- Modes of transportation and highway system.
- Economic conditions, including median income, poverty level, and job availability.
- Cultural factors and educational, recreational, and religious characteristics.
- Family conditions with respect to divorce and family cohesiveness.
- Effective strength of law enforcement agencies.
- Administrative and investigative emphases of law enforcement.
- Policies of other components of the criminal justice system (i.e., prosecutorial, judicial, correctional, and probational).
- Citizens' attitudes toward crime.
- Crime reporting practices of the citizenry.
Crime in the United States provides a nationwide view of crime based on statistics contributed by local, county, state, tribal, and federal law enforcement agencies. Population size is the only correlate of crime presented in this publication. Although many of the listed factors equally affect the crime of a particular area, the UCR Program makes no attempt to relate them to the data presented. The data user is, therefore, cautioned against comparing statistical data of individual reporting units from cities, counties, metropolitan areas, states, or colleges or universities solely on the basis on their population coverage or student enrollment. Until data users examine all the variables that affect crime in a town, city, county, state, region, or college or university, they can make no meaningful comparisons."
