As of the 2020 United States census, Arizona had a population of 7,151,502.[2]
A past census found that the population had seen 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 7,278,717 in 2019.[3]
The population density of the state is 45.2 people per square mile.[4] In 2010, there were an estimated 460,000 undocumented immigrants in the state.[5] These constituted an estimated 7.9% of the population.[6]
The center of population of Arizona is located in Maricopa County,[7] which contains over 61% of Arizona's population.
