2000 Census Tract
Census tracts in the United States, Puerto Rico, and th eVirgin Islands of the United States generally have between 1,500 and 8,000 people, with an optimum size of 4,000 people. Counties and statistically equivalent entities with fewere than 1,500 people have a single census tract. When first delineated, census trafcts are designed to be relatively homogeneous with respect to population characteristics, economic status, and living conditions. The spatial size of census tracts varies widely depending on the desnsity of the setttlement. Census tract boundaries are delineated withe he intention of being maintained over many decades so that statistical comparisions can be made from decennial census to decennial census. However, physical changes may require ocassional revisions. In addition, census tracts ocasionally are split due to population growth or combined as a result of substantial population decline.
Census tracts are identified by a four-digit basic number and may have a two-digit numeric suffix. Census tract numberrs range from 1 to 9999 and are unique within a county or statistically equivalent entity.
