of invasive plant species, restoring prairies and bur oak savanna habitats, and managing the whitetail deer population. Omaha is home to several hospitals, mostly along Dodge Street (US6). Being the county seat, it is also the location of the county courthouse. Neighborhoods Omaha is generally divided into six geographic areas: Downtown, Midtown, North Omaha, South Omaha, West Omaha, and East Omaha. West Omaha includes the Miracle Hills, Boys Town, Regency, and Gateway areas. The city has a wide range of historical and new neighborhoods and suburbs that reflect its socioeconomic diversity. Early neighborhood development happened in ethnic enclaves, including Little Italy, Little Bohemia, Little Mexico and Greek Town. According to U.S. Census data, five European ethnic enclaves existed in Omaha in 1880, expanding to nine in 1900. Around the start of the 20th century. the City of Omaha annexed several surrounding communities, including Florence, Dundee and Benson. At the same time, the city annexed all of South Omaha, including the Dahlman and Burlington Road neighborhoods. From its first annexation in 1857 (of East Omaha) to its controversial annexation of Elkhorn in 2007, Omaha has continually had an eye towards growth. Starting in the 1950s, development of highways and new housing led to the movement of the middle class to suburbs in West Omaha. Some of the movement was designated as white flight from racial unrest in the 1960s. Newer and poorer migrants lived in older housing close to downtown; those residents who were more established moved west into newer housing. Some suburbs are gated communities or have become edge cities. Recently, Omahans have made strides to revitalize the downtown and Midtown areas with the redevelopment of the Old Market, Turner Park, Gifford Park, and the designation of the Omaha Rail and Commerce Historic District.
