Flagler County in Florida, located along the Atlantic Coast between Daytona Beach and Jacksonville, was the fastest-growing county for the second year in a row with a 10.7 percent population increase from July 1, 2004, to July 1, 2005, according to estimates released today by the U.S. Census Bureau. Flagler, with 76,410 residents, also led the nation with a 53 percent population increase since Census 2000.
According to the estimates, all but one of the top-10 fastest-growing counties between 2004 and 2005 are located in either the South or the West, with Lyon, Nev. (near Carson City), ranking second at 9.6 percent; Kendall, Ill. (in the Chicago area), third at 9.4 percent; Rockwall, Texas (near Dallas), fourth; Washington, Utah (the lone county in the St. George metro area), fifth; Nye, another Nevada county, sixth at 7.4 percent; and Pinal, Ariz. (near Phoenix), seventh at 6.9 percent.
Rounding out the top 10 were three counties in Virginia: Loudoun, near Washington, D.C., ranked eighth with a population increase of 6.8 percent; King George, ninth with 6.7 percent; and Caroline (near Richmond) 10th at 6.5 percent. Another Chicago-area county — Grundy, Ill., just missed the top 10, ranking 11th. (See Table 1. Excel | PDF)
