The UCR
The NCVS
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 uniform crime report's pros are that the final data is independent of population and readily available. The major con is that it is based only on reported crimes. There is no way to quantify crimes that go unreported. The national crime victimization survey focuses on unreported crime by asking people if they've been victimized and whether they reported it. Although this is a large pro, a con is that it is easy for the people being interviewed to lie.
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.
One pro is that the Uniform Crime Report is standardized, so the results from across the nation are comparable. Another pro is that it uses the official police reports. A con is that it overlooks unreported crime.

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.
The Uniform Crime Reports (UCR) and the National Incident-Based Reporting System (NIBRS) of the 1950s offered valuable data on crime statistics, allowing for a standardized way to compare crime rates across jurisdictions. Pros included improved law enforcement resource allocation and public awareness of crime trends. However, cons included limited data scope, as UCR primarily focused on reported crimes and excluded many offenses, while NIBRS, though more detailed, struggled with inconsistent reporting and participation from law enforcement agencies. Additionally, both systems faced challenges in addressing the complexities of certain crimes, leading to potential misinterpretations of crime trends.
NIBRS is a system for reporting crime that is being used by more police agencies every year. UCR is the old method for collected less specific data than NIBRS and the report that comes out yearly with the analyzed data. Cons to these systems include that both of these systems only collect data on reported crime and that the UCR collection only allows for one crime to be reported per incident. A pro is that that the information is standardized across the US.
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.
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.
