The UCR
The NCVS
The Uniform Crime Report (UCR) is a program run by the FBI that collects data on crimes reported to law enforcement agencies, providing statistics on crime rates. The National Crime Victimization Survey (NCVS) is conducted by the Bureau of Justice Statistics and surveys individuals to gather information on crime victims and their experiences, including crimes not reported to the police.
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.
The Uniform Crime Report (UCR) provides consistent data for comparison, but it may underreport crimes or not capture all types of offenses. The National Incident-Based Reporting System (NIBRS) offers more detailed and accurate data on crimes, but its implementation can be costly and time-consuming for law enforcement agencies.
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.
UCR (Uniform Crime Reporting) is a summary-based reporting system that collects data on crimes reported to law enforcement agencies. NIBRS (National Incident-Based Reporting System) provides detailed information about each crime incident, including victim and offender demographics. NCVS (National Crime Victimization Survey) collects data on crimes experienced by individuals, including those that are not reported to the police.
The uniform crime report allows people to compare crime rates between different place. Some strengths are that the final data is independent of population, and will be readily available to the American public within a year. Some weaknesses are that it only covers crime that the police discover, and is not the most detail that could be reported.
The FBI prepares the UCR. They get the data for the UCR from the state police. The state police oversee the local police collecting the data.
