Crime mapping is used by analysts in law enforcement agencies to map, visualize, and analyze crime incident patterns. It is a key component of crime analysis and the CompStat policing strategy. Mapping crime, using Geographic Information Systems (GIS), allows crime analysts to identify crime hot spots , along with other trends and patterns.
Crime hotspots are areas that have high crime intensity. These are usually visualized using a map. They are developed for researchers and analysts to examine geographic areas in relation to crime. Researchers and theorists examine the occurrence of hotspots in certain areas and why they happen, and analysts examine the techniques used to ...
Buffer analysis. In geographic information systems (GIS) and spatial analysis, buffer analysis is the determination of a zone around a geographic feature containing locations that are within a specified distance of that feature, the buffer zone (or just buffer). [1] A buffer is likely the most commonly used tool within the proximity analysis ...
Violent crime rate per 100k population by state (2023) [1] This is a list of U.S. states and territories by violent crime rate. It is typically expressed in units of incidents per 100,000 individuals per year; thus, a violent crime rate of 300 (per 100,000 inhabitants) in a population of 100,000 would mean 300 incidents of violent crime per year in that entire population, or 0.3% out of the total.
Geographic profiling is a criminal investigative methodology that analyzes the locations of a connected series of crimes to determine the most probable area of offender residence. By incorporating both qualitative and quantitative methods, it assists in understanding spatial behaviour of an offender and focusing the investigation to a smaller ...
The National Crime Information Center (NCIC) is the United States' central database for tracking crime-related information. The NCIC has been an information sharing tool since 1967. [1] It is maintained by the Criminal Justice Information Services Division (CJIS) of the Federal Bureau of Investigation (FBI) and is interlinked with federal ...
A Crime concentration is a spatial area to which high levels of crime incidents are attributed. A crime concentration can be the result of homogeneous or heterogeneous crime incidents. Hotspots are the result of various crimes occurring in relative proximity to each other within predefined human geopolitical or social boundaries.
The following table of United States cities by crime rate is based on Federal Bureau of Investigation Uniform Crime Reports (UCR) statistics from 2019 for the 100 most populous cities in America that have reported data to the FBI UCR system. [1] The population numbers are based on U.S. Census estimates for the year end.
