of immigration, migration, and expansion, the city reached its peak population in 1950. That year, the Census Bureau reported St. Louis's population as 82% White and 17.9% African American. After World War II, St. Louis began losing population to the suburbs, first because of increased demand for new housing, unhappiness with city services, ease of commuting by highways, and later, white flight. St. Louis's population decline has resulted in a significant increase of abandoned residential housing units and vacant lots throughout the city proper; this blight has attracted much wildlife (such as deer and coyotes) to the many abandoned overgrown lots. St. Louis has lost 64.0% of its population since the 1950 United States census, the highest percent of any city that had a population of 100,000 or more at the time of the 1950 Census. Detroit, Michigan, and Youngstown, Ohio, are the only other cities that have had population declines of at least 60% in the same time frame. The population of the city of St. Louis has been in decline since the 1950 census; during this period the population of the St. Louis Metropolitan Area, which includes more than one county, has grown every year and continues to do so. A big factor in the decline has been the rapid increase in suburbanization. According to the 2010 United States census, St. Louis had 319,294 people living in 142,057 households, of which 67,488 households were families. The population density was 5,158.2 people per square mile (1,990.6/km). About 24% of the population was 19 or younger, 9% were 20 to 24, 31% were 25 to 44, 25% were 45 to 64, and 11% were 65 or older. The median age was about 34 years. The African-American population is concentrated in the north side of the city (the area north of Delmar Boulevard is 94.0% black, compared with 35.0% in the central corridor and 26.0% in the south side of St. Louis). Among the Asian-American population in the city, the largest ethnic group is Vietnamese (0.9%), followed by Chinese (0.6%) and Indians (0.5%). The Vietnamese community has concentrated in the Dutchtown neighborhood of south St. Louis; Chinese are concentrated in the Central West End. People of Mexican descent are the largest Latino group, and make up 2.2% of St. Louis's population. They have the highest concentration in the Dutchtown, Benton Park West (Cherokee Street), and Gravois Park neighborhoods. People of Italian
