Metro Atlanta, designated by the United States Office of Management and Budget as the Atlanta-Sandy Springs-Roswell, GA Metropolitan Statistical Area, is the most populous metro area in the US state of Georgia and the ninth-largest metropolitan statistical area (MSA) in the United States. It is the core of the broader Atlanta--Athens-Clarke--Sandy Springs Combined Statistical Area. Its economic, cultural, and demographic center is Atlanta, Georgia's capital and largest city. The Atlanta Combined Statistical area spans up to 39 counties in north Georgia and had an estimated population of 6.1 million people.〔US Census Bureau, "Largest US Metropolitan Areas by Population, 1990-2010", in ''World Almanac and Book of Facts 2012'', p. 612.〕 Atlanta is considered an "alpha(-) world city". It is the third largest metropolitan region in the Southeast behind Greater Washington and South Florida. ==Definitions== By U.S. Census Bureau standards, the population of the Atlanta region spreads across a metropolitan area of – a land area comparable to that of Massachusetts. Because Georgia contains more counties than any other state except Texas (explained in part by the now-defunct county-unit system of weighing votes in primary elections), area residents live under a heavily decentralized collection of governments. As of the 2000 census, fewer than one in ten residents of the metropolitan area lived inside Atlanta city limits. A 2006 survey by the Metro Atlanta Chamber of Commerce counted 140 cities and towns in the 28‑county Metropolitan Statistical Area in mid-2005.〔 Six cities – Johns Creek (2006), Milton (2006), Chattahoochee Hills (2007), Dunwoody (2008), Peachtree Corners (2011), and Brookhaven (2012) – have incorporated since then, following the lead of Sandy Springs in 2005. The Atlanta metropolitan area was first defined in 1950 as Fulton, DeKalb, Gwinnett, Cobb and Clayton counties. Butts, Cherokee, Douglas, Fayette, Forsyth, Henry, Newton, Rockdale and Walton counties were added after the 1970 census, with Barrow and Coweta counties joining in 1980 and Bartow, Carroll, Paulding, Pickens and Spalding counties in 1990. Atlanta's larger combined statistical area (CSA) adds the Gainesville, Georgia MSA, Athens-Clarke County, Georgia MSA and the LaGrange, Thomaston, Jefferson, Calhoun, and Cedartown micropolitan areas, for a total 2012 population of 6,162,195. The CSA also abuts the Macon and Columbus MSAs. The region is one of the metropolises of the Southeastern United States, and is part of the emerging megalopolis known as Piedmont Atlantic MegaRegion along the I-85 Corridor, "Charlanta" colloquially. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Atlanta metropolitan area」の詳細全文を読む スポンサード リンク
