Wiki Version:
The Crime Open Database (CODE) is a service that makes it convenient to use crime data from multiple US cities in research on crime. All the data are available to use for free as long as you acknowledge the source of the data. Cities are included in CODE if they release incident-level crime data that: * can be re-used under an [open-data license](, * include the location of each crime (possibly with some deliberate error introduced by the city to protect victims' privacy), * include the date on which each crime occurred, * include a code or category that can be used to create a consistent set of crime types across cities, * provide data for at least four consecutive years, * pass basic checks on the quality of the data. At present, CODE includes data from 21 cities out of [the 50 largest cities in the United States]( * Austin, TX * Boston, MA * Charlotte, NC * Chicago, IL * Colorado Springs, CO * Detroit, MI * Fort Worth, TX * Houston, TX * Kansas City, MO * Los Angeles, CA * Louisville, KY * Memphis, TN * Mesa, AZ * Minneapolis, MN * Nashville, TN * New York, NY * San Francisco, CA * Seattle, WA * St Louis, MO * Tucson, AZ * Virginia Beach, VA [Reasoning for why other cities are not included]( is available on GitHub.
