The Uniform crime report takes data from every police station in the United States. It divides the crimes into different categories, the two main categories being violent and property crime. It takes the data nad the population of the place it si from, and comes up with a crime rate which can compare small towns to large cities.

Index crimes are a key unit of analysis in the Uniform Crime Reporting (UCR) program. The UCR program collects data on crimes reported to law enforcement agencies across the United States, including crimes such as murder, robbery, burglary, and aggravated assault.
The UCR only counts reported crime, and cannot speak for crime that is unreported.The UCR has 8 index crimes, and only counts crimes which fall into these categories.The UCR is not very detailed, and there are more detailed and accurate methods of reporting the data, such as NIBRS.
The Uniform Crime Report is compiled from all U.S. police stations by the FBI, while the National Crime Victimization Survey is compiled from a phone survey. The UCR only counts reported crime, while the NCVS counts both reported and unreported. The UCR is compiled by people who are familiar with the vocabulary used to define crime, while the NCVS is compiled by people who have less knowledge of it.

The two major sources of crime statistics in the US are the Federal Bureau of Investigation's Uniform Crime Reporting (UCR) Program and the Bureau of Justice Statistics' National Crime Victimization Survey (NCVS). The UCR compiles reported crimes from law enforcement agencies across the country, focusing on trends in serious offenses. In contrast, the NCVS gathers data through surveys of individuals, capturing unreported crimes and providing insights into victims' experiences. Together, these sources offer a comprehensive view of crime in the United States.

Statistically there is none - because no one has ever complied a comprehensive list of so-called "victimless crimes" or described what they are.
More than 20% are cleared by arrest.
The uniform crime report is compiled by the FBI to allow people to compare crime rate between cities and over time. For example, crime rates from New York City can be compared to the crime rates in a small town.The strengths:The final data is independent of population and is readily available to everybody.The data is taken from all police stations in the United States.The UCR differentiates between violent and property crime, so larceny is not on the same level as rape.The weaknesses:The UCR only counts the crimes that are reported to the police, and is not the most detailed picture of crime possible in some areas. Some crimes are not reported when the victim either feels it's unimportant or is embarrassed to talk about it, and so that crime is not a part of the crime rate.Only counts 8 specific crimes. (There are 4 violent index crimes and 4 property index crimes.)The UCR is not very detailed. It reflects crimes in each category, but not other circumstances affecting the incident.The UCR is prone to small errors, For example, if a crime is labeled wrong it is discounted.

The Uniform Crime Reporting (UCR) program operates by collecting and analyzing crime data from law enforcement agencies across the United States. Participating agencies voluntarily submit data on various crimes to the FBI, which then compiles the information and publishes annual reports on crime trends. The UCR is a valuable tool for tracking crime patterns and informing law enforcement policies and strategies.
