Only California and Oklahoma have more Native Americans. The perimeters of Phoenix, Tucson, Prescott, Scottsdale, Flagstaff and Yuma border on Native American reservations.
The largest ancestry groups in Arizona are Mexican, German, English, Irish, and Native American. 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 non-Hispanic White Americans. The northeastern part of Arizona has many American Indians. 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. 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, 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 the other races accounted for 14% of births.
