Pomona is a city located in the Pomona Valley between the Inland Empire and the San Gabriel Valley with a population of 149,058 at the 2010 census, making it the seventh largest city in Los Angeles County.
Founded in 1875 and incorporated in 1888, the City was promoted as an agricultural and ranching centre. Pomona was named for the Roman goddess of fruit that grows on trees. Development was sustained by railroad links and artesian irrigation. Winemaking soon became important in the city but was replaced by citrus and olive growing in the late 19th century. By the mid-20th century, rapid residential and industrial growth paralleled the expansion of the Los Angeles metropolitan area. By the beginning of the 21st century, the City had developed into a diversified economy.
The City is the site of the Fairplex, which hosts the L.A. County Fair and the Pomona Swap Meet & Classic Car Show. The swap meet (for car parts and accessories) is part of the car show, which is a single-day event held seven times throughout the year. The City is also home to the NHRA Auto Club Raceway at Pomona (formerly the Pomona Raceway), which hosts Winternationals drag racing competition.
