The Wholesale District or more recently[when?] the Warehouse District, of Los Angeles is a group of warehouses located in the southeast part of Downtown Los Angeles. Most of the warehouses are industrial in nature and serve the greater Los Angeles area.[not in citation given] Few people live in this neighborhood now, though at one time[when?] the area had a substantial African-American population. The warehouses are located along the BNSF and UPRR rail lines, which run along Alameda Street and the Los Angeles River. Part of the Wholesale District extends into the city of Vernon, California.
