According to Census 2000, 281.4 million people were counted in the United States — 143.4 million of whom were female and 138.1 million male.1 The former made up 50.9 percent of the population, compared with 51.3 percent in 1990.
Information on gender was derived from a question which was asked of all people (see Figure 1). A question on the sex of individuals was included in all censuses since the first one in 1790.
This report, part of a series that analyzes population and housing data collected by Census 2000, presents the number who are male and female in regions, states, counties, and places of 100,000 or more and highlights comparisons with data from the 1990 census.2
