How does the UCR compile its data?

The Federal Bureau of Investigation publishes the Uniform Crime Reporting (UCR) program, which aggregates official statistics on crime in the United States (FBI). The FBI does not collect the information. Rather, law enforcement departments around the country provide data to the FBI, which compiles the reports. Each state has its own police department and so each state's UCR figures are different from those of other states.

Crime statistics are gathered by local police departments on forms provided by the FBI. The forms ask for information about each incident reported. Officers must record the time of the offense, the date, and a description of the area where the crime occurred. They may also report information such as the type of weapon used, the amount of money taken, and the number of victims involved.

Each year, police departments receive funds from their local governments to hire more officers and improve community policing programs. These programs aim to reduce crime by making it easier for officers to interact with residents and by providing services to areas with high rates of crime.

What is the UCR program?

The Uniform Crime Providing Program (UCR) is a countrywide, collaborative statistical endeavor involving more than 18,000 law enforcement agencies reporting statistics on crimes brought to their notice voluntarily. The information is used by officials to guide crime prevention efforts and identify areas where police resources are most needed.

The UCR program began in 1948 when President Harry S. Truman ordered that federal laws be included in the survey. Before this time, national statistics were not available at all because states did not share crime information with each other or the federal government.

Since its inception, the UCR has become one of the primary sources of data for researchers, policy makers, and the general public about crime in the United States. Agencies participating in the UCR program collect information on all types of offenses committed within their jurisdictions. This includes arrests for both felony and misdemeanor crimes, as well as reports of stolen vehicles, weapons, and other items taken during burglaries and thefts.

Crime statistics are collected by local law enforcement agencies and submitted electronically to the FBI through a voluntary system known as "311 calls." Each agency has its own unique calling procedure but generally requires only an email address to report crime statistics online. Agencies may also send hard copy reports if they choose.

Where does the UCR get its data?

Data from over 18,000 city, university, and college law enforcement agencies, as well as county, state, tribal, and federal law enforcement agencies, are included in the UCR Program. Agencies volunteer to join and report crime data either through a state UCR program or directly to the FBI's UCR Program.

Each agency that volunteers data is required to submit monthly reports of criminal activity within their jurisdiction. These reports include information on arrests, charges, and types of crimes committed. The UCR Program also requests information on missing persons and unidentified remains.

Crime statistics are available for download from the FBI's website. The latest data can be found at

Uniform Crime Reports provide data on thousands of cities and counties across the United States. They show how often crimes are committed in each jurisdiction and allow us to make estimates about what might happen in larger areas without conducting our own studies. Although crime statistics cannot predict what will happen in any particular case, they can help identify trends that may indicate future risk. For example, crime statistics show that murder rates are generally higher in large cities such as New York or Chicago than in smaller towns, but they also show that these rates vary greatly between individual cases. This means that no two cases of murder are alike - something that cannot be determined from observing just one or a few examples.

What are the weaknesses of the UCR?

The FBI Uniform Crime Report's (UCR) "murder and nonnegligent manslaughter" data are so skewed that the only figures criminologists can rely on are the number of deaths investigated by police as potentially criminal homicides, as well as the weapons use data reported by the UCR and the National Crime Survey (...).

The main weakness of the UCR is its reliance on voluntary reporting by law enforcement agencies. Murder is a subjective term, and not all killings will be considered criminal homicides by police departments. Police investigations of many crime scenes may conclude with no charges filed or an indictment dismissed in court. This may occur for a variety of reasons, such as lack of evidence, errors made by prosecutors during the course of a case, or decisions by judges at trial to dismiss charges.

For example, between 2008 and 2012, nearly half of all murders reported in San Francisco were classified by police as "unknown causes". There was also a large increase in the number of shootings reported, from 3,175 in 2008 to 5,443 in 2012. The rise in shooting incidents was likely due to more guns being sold to civilians after Congress passed a law allowing people to buy unlimited amounts of ammunition.

Another problem with the UCR is that it includes counts of violent crimes that do not result in death.

How do I access the UCR?

Explorer of Crime Data (CDE) CDE allows law enforcement and the general public to quickly access, view, and comprehend large volumes of UCR data collected and released by the FBI UCR Program. The CDE publishes UCR statistics quarterly. Below are links to historical UCR publications (up to and including 2019). Additional UCR publications will be added as they become available.

Why was the UCR created?

UCR's Historical Background Recognizing the need for national crime data, the IACP established the Committee on Standard Crime Records in the 1920s to create a system of uniform crime statistics. In 1979, arson was introduced as the eighth Part I criminal category by congressional legislation.

The committee developed guidelines for police departments to use in reporting crimes. The guidelines were revised in 1987 to include audio and video recording equipment. They provide the basis for how crimes are reported today.

After the release of the first federal census in 1790, an effort was made by Congress to establish a standard method for counting inhabitants. This effort failed because there was no way to enforce it. From that time forward, each new census has required a new determination of population. As populations changed, so too did estimates of the percentage of people in various income groups. These percentages determined how much money could be given back to the states under the old formula for allocating funds to their representatives in Congress.

In the mid-20th century, civil rights activists sought improved statistics on racial discrimination. The National Advisory Commission on Civil Disorders, also known as the Kerner Commission after its chairman, called for increased funding to address poverty, racism, and violence against women. Police agencies across the country adopted the NCIC code system, which allowed for electronic communication between law enforcement agencies. This led to a significant increase in information sharing about criminals and crime scenes.
