*A census tract is a geographic area defined by the United States Census Bureau and used for the census. A census tract normally covers a smaller area than a city or zip code. On average, a census tract has around 4,200 residents. Census tracts are more uniformly distributed in terms of the number of residents than cities or zip codes. Also, the census tract demographic data is nearly 100% complete vs. less than 70% coverage of demographic data for cities and zip codes. Therefore using census tracts is an excellent way to compare and study smaller scale locations inside and across multiple states. For example understanding the different areas of a large city or comparing neighborhoods in one city to neighborhoods in another city. Census tracts can be further divided into census block groups and then finally census blocks for understanding locations in a block and a community level respectively.
