The Research Triangle, commonly referred to as simply The Triangle, is a region in the Piedmont of North Carolina in the United States, anchored by North Carolina State University, Duke University, University of North Carolina at Chapel Hill, and the cities of Raleigh and Durham and the towns of Cary and Chapel Hill. The eight-county region, officially named the Raleigh–Durham–Cary-Chapel Hill combined statistical area (CSA), comprises the Raleigh-Cary and Durham–Chapel Hill metropolitan areas and the Dunn, Henderson, Oxford, and Sanford Micropolitan Statistical Areas. A 2013 Census estimate put the population at 2,037,430, making it the second largest metropolitan area in the state of North Carolina behind Charlotte. The Raleigh–Durham television market includes a broader 24-county area which includes Fayetteville, and has a population of 2,726,000 persons.〔Nielsen Station Index, Viewers in Profile, Raleigh–Durham (Fayetteville), NC May 2010〕 The "Triangle" name was cemented in the public consciousness in the 1950s with the creation of Research Triangle Park, home to numerous high-tech companies and enterprises. Although the name is now used to refer to the geographic region, "the Triangle" originally referred to the universities, whose research facilities, and the educated workforce they provide, have historically served as a major attraction for businesses located in the region. The region should not be confused with The Triad, which is a North Carolina region adjacent to and directly west of the Triangle comprising Greensboro, Winston-Salem, and High Point, among other cities. Most of the Triangle is part of North Carolina's second, fourth, and thirteenth congressional districts. == Counties == Depending on which definition of the Research Triangle region is used, as few as three or as many as 16 counties are included as part of the region. All of these counties when included hold a population over 2,167,000 people. *Chatham‡¶ *Durham *‡¶ *Edgecombe¶ *Franklin‡¶ *Granville‡¶ *Harnett‡¶ *Johnston‡¶ *Lee‡¶ *Moore¶ *Nash‡¶ *Orange *‡¶ *Person‡¶ *Vance‡¶ *Wake *‡¶ *Warren¶ : * :‡ - U.S. Census Bureau definition, taken from the counties included in the Raleigh–Durham–Cary-Chapel Hill Combined Statistical Area :¶ - Most liberal definition of the Research Triangle region, as defined by the Research Triangle Regional Partnership Raleigh–Durham–Cary-Chapel Hill Combined Statistical Area Population (Census Estimates 2014) 2,075,126 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「Research Triangle」の詳細全文を読む スポンサード リンク
