Our friends at Wikipedia describe it this way:
Omaha is the largest city in the U.S. state of Nebraska and the county seat of Douglas County. Omaha is in the Midwestern United States on the Missouri River, about 10 mi (15 km) north of the mouth of the Platte River. The nation’s 39th-largest city, Omaha’s 2020 census population was 486,051.
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.
