West of downtown, across Van Ness Avenue, lies the large Western Addition neighborhood, which became established with a large African American population after World War II. The Western Addition is usually divided into smaller neighborhoods including Hayes Valley, the Fillmore, and Japantown, which was once the largest Japantown in North America but suffered when its Japanese American residents were forcibly removed and interned during World War II. In the south-east quadrant of the city is the Mission District—populated in the 19th century by Californios and working-class immigrants from Germany, Ireland, Italy, and Scandinavia. In the 1910s, a wave of Central American immigrants settled in the Mission and, in the 1950s, immigrants from Mexico began to predominate. In recent years, gentrification has changed the demographics of parts of the Mission from Latino, to twenty-somethingprofessionals living the hipster lifestyle. Noe Valley to the southwest and Bernal Heights to the south are both increasingly popular among young families with children. East of the Mission is the Potrero Hill neighborhood, a mostly residential neighborhood that features sweeping views of downtown San Francisco. West of the Mission, the area historically known as Eureka Valley, now popularly called the Castro, was once a working-class Scandinavian and Irish area. It has become North America's first and best known gay village, and is now the center of gay life in the city. Located near the city's southern border, the Excelsior District is one of the most ethnically diverse neighborhoods in San Francisco. The predominately African American Bayview-Hunters Point in the far southeast corner of the city is one of the poorest neighborhoods and suffers from a high rate of crime, though the area has been the focus of controversial plans for urban renewal.
