 is 25 rather than 1,000. Many CDPs correspond to the boundaries established for Alaska Native village statistical areas (ANVSAs), which represent the geographic jurisdiction of an Alaska Native village (see, “American Indian and Alaska Native Areas”). The population size required in UAs is the same as in the remainder of the United States, but there were no such CDPs in 1990.

The Census Bureau has always noted that the population settlements in Hawaii were unincorporated. The published data before 1980, however, showed the unincorporated communities as cities, towns, or villages, and treated the places as incorporated. Beginning in 1980, all places in Hawaii were shown as CDPs. The consolidated City and County of Honolulu dates from 1907, but the Census Bureau, in agreement with local authorities (after 1960, with the Office of the Governor) treats the built-up portion of the city as a CDP (more or less coextensive with the old Honolulu judicial district) and identifies other CDPs within Honolulu County.

The minimum population for a CDP in Hawaii is 300, regardless of whether it is inside or outside of a UA. Soon after becoming a State, the Hawaii legislature enacted State Bill 1122 (Act 25 of 1963) for the purpose of establishing statistical boundaries for its cities and towns. Those entities lack the governmental powers that define incorporated places in the other 49 States, but Hawaii wanted the Census Bureau to recognize entities it defined as the equivalent of mainland incorporated places for statistical purposes. The Census Bureau corresponded with the Office of the Governor before the enactment of the legislation, and agreed to the 300 population cutoff.

In Puerto Rico, which has no incorporated places, the Census Bureau defines two kinds of CDPs—zonas urbanas (urban zones) and comunidades (villages). Zonas urbanas, roughly equivalent to county seats in the United States, are the seats of government for the municipios, which are the statistical equivalents of U.S. counties. Comunidades, which were known as aldeas in the 1980 and earlier censuses, require a minimum Places9-27
