Well i think its police and the FBI that collect the crime statistics (sorry if that is not your question)
In 1930, Congress established the Federal Bureau of Investigation (FBI) to serve as a national clearinghouse for crime statistics. This initiative aimed to collect, analyze, and disseminate crime data from various jurisdictions across the United States. The FBI's Uniform Crime Reporting (UCR) Program was launched as part of this effort, providing a standardized method for law enforcement agencies to report crime statistics. This initiative has played a crucial role in understanding crime trends and informing policy decisions.
It is a report published by the FBI detailing the overal crime statistics as reported to them by local law enforcement agencies.See below link:
Crime reporting is the reporting of crimes that happen in a particular area of a neighborhood, city, state or country. Crime reporting can include things like crime statistics.
The crime index is otherwise called crime statistics. It is a statistic measurement of crime or crime rate in a particular society, community, country or simply a region. It is mainly used by agencies like FBI in the US, Home Office in England and Wales, Interpol and UN. They mainly collect these information either from Uniform crime reports or individual survey, relaying one their honesty. So the results may not be 100% accurate, but it could give you more or less exact figures to analyse.
The FBI collect the information for the UCR. They collect from the State police. The state police collect it from local police, who gather the information themselves as they investigate crimes.
Statistics is used to collect data on many aspects of our population that include: pregnancy, rape, violence, divorce, health, crime, and many many others.
Not clear what the questioner is asking. (For the US )By accessing the FBI website you can see the results of gathering the Uniform Crime Reporting Statistics summarized quite nicely. See below link.
Check the FBI Uniform Crime Report link on the FBI web site.
The Uniform Crime Reports (UCR) published by the FBI are based on data collected from law enforcement agencies across the United States. These agencies voluntarily report crimes that occur in their jurisdictions, including statistics on offenses such as murder, robbery, and aggravated assault. The UCR aims to provide a comprehensive overview of crime trends and patterns at the national, state, and local levels. Data is typically reported on a monthly basis, contributing to an annual summary of crime statistics.
Report it to your local police department first. If it's a crime which falls into the FBI's jurisdiction, then the PD will forward it to the FBI.
Crime is committed, and the numbers that measure it are collected, analyzed and become statistics.
