The U.S. Census Bureau's 2010 Census Profile maps present a graphic overview of selected demographic information from the 2010 Census of Population and Housing. In addition to a population density map, each page includes a pie chart showing percent of total population by race, a population pyramid, and a bar chart illustrating housing occupancy rates. The map series consists of one page-sized map for each state in the United States, the District of Columbia, and Puerto Rico, as well as a national map.
