What is census tract population?
Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people. A census tract usually covers a contiguous area; however, the spatial size of census tracts varies widely depending on the density of settlement.
What is the difference between ZIP code and census tract?
Census tracts are polygons and cover a well-defined geographic area. ZIP codes are clusters of lines; the U.S. Postal Service does not define ZIP Code boundaries. Census tracts provide more granularity (73,000 areas) than ZIP Codes (43,000).
Why do some areas not have zip codes?
In some cases, Zip codes have no physical location because they are assigned to a mobile or abstract “location” such as a military ship. Even in the most common case of Zip codes assigned to streets, Zip codes do not clump together in groups that may be covered by rational polygons.
