Largo is the third largest city in Pinellas County, Florida, United States, and is part of the Tampa Bay Area. As of the 2010 census, the city had a population of 77,648, up from 69,371 2000.
The Town of Largo was incorporated in 1905. Lake Largo was drained in 1916 to make way for growth and development. Between 1910 and 1930, Largo's population increased about 500%. Then and for decades afterwards, Largo's economy was based on agriculture—citrus groves,cattle ranches, and hog farms, as well as turpentine stills and sawmills. Largo is best remembered as "Citrus City", from the time it was a citrus packing, canning and shipping center. The Great Depression was unkind to Largo. Largo lacked the financial resources to meet its obligations. Largo reverted to its 1913 boundaries and charter. The population dropped approximately 30%. The debt incurred by the issuance of bonds in the late 1920s was not paid off until after World War II.
