City-Data is an Illinois-based social networking and information website that presents data and information pertaining to United States cities, and offers public online forums for discussion.
US cities, counties, zip codes, and neighborhoods are profiled and compared using governmental data about race, income, education, crime, weather, housing, maps, air pollution, and religions.
The site contains information about home value estimates (including recent home sales), local businesses, schools (including their demographics and test scores), hospitals, libraries, tourist attractions, local businesses, restaurant inspection findings, building permits, bridge conditions, hotels, water systems, airports, cell phone towers, property tax assessments, and car accidents.
The information on the website includes consumer names and street addresses, obtained via FOIA requests and other public records; City-Data has an opt-out feature[1] to break the web-visible association between names and street addresses, but does not remove the consumer names themselves.
[2] City-Data has been featured in articles and listicles as a way for potential newcomers to learn more about particular cities.
