The U. S. Census Bureau has produced a 1990 Population Distribution in the United States map (also referred to as the "Nighttime Map") as part of the GE-90 map series (GE-90 No. 5). In this map series Alaska and Hawaii, shown in the upper left and lower left map corners respectively, are in more relative positions to the conterminous U.S. than in earlier map series.
The 1990 version of the Population Distribution of the United States map reflects population data from the 1990 Decennial Census. The U.S. land area is shown in black against a midnight blue background in which the population locations are shown as if lights were visible during the night sky. White dots coalesce to form the urban population concentrations. Each white "dot" represents 7,500 persons.
