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 annual UCR(Uniform Crime Report) is based upon arrest data which law enforcement agencies in the US report to the FBI. The annual NCVS(National Crime Victims Survey) is based upon data which crime victims voluntarily report to the Bureau of Justice Stastics within the US Department of Justice.

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.
NCVS
No system for collecting crime rates is perfect. The UCR could improve the value of the crime rates it produces by factoring in unreported crime. The NIBRS could improve the value of the crime reports it leads to by being implemented across the US.
I'm not expert, but UCR has been used for decades to collect some basic info on every crime within its categories (major crimes). NIBRS is a newer initiative that tracks more detailed information, allowing for multiple vicims, multiple offenders,etc in order to capture more detailed info about each incident. Once implemented, more detailed questions can be answered about crime rather than jsut basic amanac statistics. ncvs is a random probability survey asked of household to determine if anyone has been the vicim of a crime. Thus its a better measure of the liklihood of being a victim that often inaccurate ccomplete inumerations such as nibs and ucr.
The Uniform Crime Report is the standard crime reporting measure. It collects data on 8 different index crimes and reports it every year. The National Incident Based Crime Reporting System still goes toward the UCR, but it collects more detailed information. The National Crime Victimization Survey is not based on police reports, instead it is based on a phone survey. It asks people if they've been victimized and whether they reported the crime.
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.
