The Census Bureau may recognize other settlements as CDPs if they have at least 300 inhabitants; six CDPs qualified for the 1980 and 1990 censuses.

The Virgin Islands were block-numbered for the first time for the 1990 census. At the request of the Virgin Islands’ government, the BGs for the 1990 census were required to have 140 to 160 housing units so that they could be designed to approximate the EDs used for the 1980 census. The Virgin Islands Planning Office delineated the BGs and then grouped them into a meaningful set of BNAs for the 1990 census; it also delineated the CDPs for the 1980 census, which were carried forward unchanged for the 1990 census. The census itself actually was conducted under the auspices of the University of the Virgin Islands.

The economic censuses report data for the Virgin Islands, each of the three major islands (first-order subdivisions), and each of the three towns (places).
