Native Americans in Arizona.

As of 2009, Arizona had a population of 6.343 million, [2] which is an increase of 213,311, or 3.6%, from the prior year and an increase of 1,035,686, or 20.2%, since the year 2000. 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. The most recent population estimates released by the US Census put the population at 6,828,065 in 2015. [3]

Arizona U.S. state in the United States

Arizona is a state in the southwestern region of the United States. It is also part of the Western and the Mountain states. It is the sixth largest and the 14th most populous of the 50 states. Its capital and largest city is Phoenix. Arizona shares the Four Corners region with Utah, Colorado, and New Mexico; its other neighboring states are Nevada and California to the west and the Mexican states of Sonora and Baja California to the south and southwest.

Human migration permanent change of residence of people

Human migration is the movement of people from one place to another with the intentions of settling, permanently or temporarily at a new location. The movement is often over long distances and from one country to another, but internal migration is also possible; indeed, this is the dominant form globally. People may migrate as individuals, in family units or in large groups.

Immigration to the United States demographic phenomenon

Immigration to the United States is the international movement of non-U.S. nationals in order to reside permanently in the country. Immigration has been a major source of population growth and cultural change throughout much of the U.S. history. Because the United States is a settler colonial society, all Americans, with the exception of the small percent of Native Americans, can trace their ancestry to immigrants from other nations around the world.


The population density of the state is 45.2 people per square mile. [4] In 2010, there were an estimated 460,000 illegal immigrants in the state. [5] These constituted an estimated 7.9% of the population. [6]

Center of population

In demographics, the centre of population of a region is a geographical point that describes a centrepoint of the region's population. There are several different ways of defining such a "centre point", leading to different geographical locations; these are often confused.

American Community Survey demographic survey in the United States

The American Community Survey (ACS) is an ongoing survey by the U.S. Census Bureau. It regularly gathers information previously contained only in the long form of the decennial census, such as ancestry, citizenship, educational attainment, income, language proficiency, migration, disability, employment, and housing characteristics. These data are used by many public-sector, private-sector, and not-for-profit stakeholders to allocate funding, track shifting demographics, plan for emergencies, and learn about local communities. Sent to approximately 295,000 addresses monthly, it is the largest household survey that the Census Bureau administers.

Black people is a skin group-based classification used for specific people with a mid to dark brown complexion. Not all black people have dark skin; however, in certain countries, often in socially based systems of racial classification in the Western World, the term black is used to describe persons who are perceived as dark-skinned compared to other populations. It is mostly used for the people of Sub-Saharan African descent, those of Arab descent and the indigenous peoples of Oceania, Southeast Asia and the Indian subcontinent.

Indigenous peoples of the Americas Pre-Columbian inhabitants of North, Central and South America and their descendants

The indigenous peoples of the Americas are the pre-Columbian peoples of North, Central and South America and their descendants.

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 [11] have more Native Americans. The perimeters of Phoenix, Tucson, Prescott, Flagstaff and Yuma border on Native American reservations.

Native Americans in the United States Indigenous peoples of the United States (except Hawaii)

Native Americans, also known as American Indians, Indigenous Americans and other terms, are the indigenous peoples of the United States, except Hawaii and territories of the United States. More than 570 federally recognized tribes live within the US, about half of which are associated with Indian reservations. The term "American Indian" excludes Native Hawaiians and some Alaskan Natives, while "Native Americans" are American Indians, plus Alaska Natives of all ethnicities. The US Census does not include Native Hawaiians or Chamorro, instead being included in the Census grouping of "Native Hawaiian and other Pacific Islander".

California U.S. state in the United States

California is a state in the Pacific Region of the United States. With 39.6 million residents across a total area of about 163,696 square miles (423,970 km2), California is the most populous U.S. state and the third-largest by area. The state capital is Sacramento. The Greater Los Angeles Area and the San Francisco Bay Area are the nation's second- and fifth-most populous urban regions, with 18.7 million and 9.7 million residents respectively. Los Angeles is California's most populous city, and the country's second-most populous, after New York City. California also has the nation's most populous county, Los Angeles County, and its largest county by area, San Bernardino County. The City and County of San Francisco is both the country's second-most densely populated major city after New York City and the fifth-most densely populated county, behind only four of the five New York City boroughs.

Oklahoma U.S. state in the United States

Oklahoma is a state in the South Central region of the United States, bordered by Kansas on the north, Missouri on the northeast, Arkansas on the east, Texas on the south and west, New Mexico on the west, and Colorado on the northwest. It is the 20th-most extensive and the 28th-most populous of the 50 United States. The state's name is derived from the Choctaw words okla and humma, meaning "red people". It is also known informally by its nickname, "The Sooner State", in reference to the non-Native settlers who staked their claims on land before the official opening date of lands in the western Oklahoma Territory or before the Indian Appropriations Act of 1889, which increased European-American settlement in the eastern Indian Territory. Oklahoma Territory and Indian Territory were merged into the State of Oklahoma when it became the 46th state to enter the union on November 16, 1907. Its residents are known as Oklahomans, and its capital and largest city is Oklahoma City.

The largest ancestry groups in Arizona are Mexican (25.8%), German (16.5%), English (10.3%), Irish (10.9%), and Native American (4.5%). [12] 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. [13] Filipino Americans are also the largest Asian American subgroup in the state.

World War II 1939–1945, between Axis and Allies

World War II, also known as the Second World War, was a global war that lasted from 1939 to 1945. The vast majority of the world's countries—including all the great powers—eventually formed two opposing military alliances: the Allies and the Axis. A state of total war emerged, directly involving more than 100 million people from more than 30 countries. The major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World War II was the deadliest conflict in human history, marked by 70 to 85 million fatalities, most of whom were civilians in the Soviet Union and China. It included massacres, the genocide of the Holocaust, strategic bombing, premeditated death from starvation and disease, and the only use of nuclear weapons in war.

Arizona is projected to become a minority-majority state by the year 2027, [14] 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.[ citation needed ] 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%. [15]
