This includes a natural increase since the last census of 297,928 people (that is 564,062 births minus 266,134 deaths) and an increase due to net migration of 745,944 people into the state. Immigration from outside the United States resulted in a net increase of 204,661 people, and migration within the country produced a net increase of 541,283 people. New population figures for the year ending July 1, 2006, indicate that Arizona is the fastest growing state in the United States, with 3.6% population growth since 2005, exceeding the growth of the previous leader, Nevada. More than half (around 58%) of the population of Arizona live in cities of 100,000 or more inhabitants, the highest proportion of any of the 50 states. The population density of the state is 45.2 people per square mile.In 2010, there were an estimated 460,000 illegal immigrants in the state. These constituted an estimated 7.9% of the population. The center of population of Arizona is located in Maricopa County.〔(【引用サイトリンク】 publisher = United States Census Bureau )〕 ==Race and ethnicity== According to the 2005-2007 American Community Survey conducted by the U.S. Census Bureau, White Americans made up 76.4% of Arizona's population; of which 59.6% were Non-Hispanic Whites. Blacks or African Americans made up 3.4% of Arizona's population; of which 3.3% were non-Hispanic blacks. American Indians made up 4.5% of the state's population; of which 4.1% were non-Hispanic. Asian Americans made up 2.3% of the state's population. Pacific Islander Americans made up 0.1% of the state's population. Individuals from some other race made up 10.8% of the state's population; of which 0.2% were non-Hispanic. Individuals from two or more races made up 2.4% of the state's population; of which 1.4% were non-Hispanic. In addition, Hispanics and Latinos made up 29.0% of Arizona's population.〔(Arizona - Fact Sheet - American FactFinder )〕〔(Arizona - ACS Demographic and Housing Estimates: 2005-2007 )〕 The state has the third highest number (and the sixth highest percentage) of Native Americans of any state in the Union. 286,680 were estimated to live in Arizona, representing more than 10% of the country's total Native American population of 2,752,158. Only California and Oklahoma〔(Arizona QuickFacts from the US Census Bureau )〕 have more Native Americans. The perimeters of Phoenix, Tucson, Prescott, Flagstaff and Yuma border on Native American reservations. The largest ancestry groups in Arizona are Mexican (25.8%), German (16.5%), English (10.3%), Irish (10.9%), and Native American (4.5%).〔(Arizona - Selected Social Characteristics in the United States: 2005-2007 )〕 The southern and central parts of the state are predominantly Mexican American, especially in Santa Cruz County and Yuma County near the Mexican border. The north-central and northwestern counties are largely inhabited by White Americans. The northeastern part of Arizona has many American Indians. The African American population of the Phoenix metropolitan area doubled between 1990 and 2005.〔(Being Black in the Valley )〕 Asian Americans also made major contributions to the development of Arizona, such as the many Chinese who arrived in the state's mines and railroads, and the fact that over 20,000 Japanese Americans, mostly residing in the Grand Avenue section of Phoenix and farming areas of southern Arizona and the Colorado River valley, were interned during World War II. As of the 2010 US Census, Arizonans who claim Filipino ancestry exceed 53,000.〔(American FactFinder - Results )〕 Filipino Americans are also the largest Asian American subgroup in the state. Arizona is projected to become a minority-majority state by the year 2027〔http://www.tucsonweekly.com/TheRange/archives/2013/06/14/hispanics-leading-minority-growth-in-az〕 if current population growth trends continue. In 2003, for the first time, there were slightly more births to Hispanics in the state than births to non-Hispanic whites. Since then, the gap has widened. In 2007, Hispanics accounted for 45% of all newborns whereas non- Hispanic whites accounted for 41% of all births. All of the other races accounted for 14% of births. However by 2011 those trends reversed. By 2011, non-Hispanic whites accounted for 45.6% of all births while Hispanics births fell to 38.9%. 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「Demographics of Arizona」の詳細全文を読む スポンサード リンク
