Downey is a city located in southeast Los Angeles County, southeast of downtown Los Angeles. It is considered part of the Gateway Cities. The city is the birthplace of the Apollo space program, and is the hometown of Richard and Katen Carpenter. It is also the home of the oldest still operational McDonald's restaurant in the world. As of the 2010 census, the city had a total population of 111,772.
Prior to the arrival of the Spanish in Alta California, the area that now comprises Downey was inhabited by the Tongva ethnic group, which came to be called the Gabrielino by the Spanish. The nearest Tongva settlements appear to have been just north and northeast of present-day Downey, although there is difficulty in locating them very precisely.The villages of Naxaaw’nga and Sehat seem to have been situated near the present-day community of Los Nietos, or perhaps farther west on sites that were lost to floods of the San Gabriel River. Chokiishnga and Huutnga are other Tongva place names that may have referred to villages in the general area north of Downey between the San Gabriel River and Rio Hondo. In all four cases, it is difficult to relate the original location descriptions, based on ranchos and land grants, to more specific sites identifiable by today's landmarks.
