Arizona Population 2018

7,123,898

Our latest estimate puts the population of Arizona at 7.12 million in 2018. This shows growth of about half a million from the official 2010 census results, which recorded a population of 6,392,017. From 1990 to 2000, Arizona was the second fastest growing state, increasing it's population by nearly 40 percent. From 2010 to 2015, Arizona was the seventh fastest growing state, posting a cumulative growth of 6.82%.

Arizona Area and Population Density

Although Arizona is the sixth largest state in the USA by area, it is the 14th largest state by population size. Since becoming the 48th state to be admitted to the USA in 1912, Arizona has grown rapidly from 200,000 people to nearly seven million today. Much of that growth has come in the past 40 years -- in 1970 there were less than two million people in Arizona.

The population of Arizona is concentrated around Phoenix, the state capital, and Tucson, the second largest city in the state. The largest county in Arizona by population count is Maricopa County, which is home to 4.1 million of the state's 6.9 million people. Containing over 60% of the state's population, Maricopa encompasses nine of the state's ten largest cities. Arizona features an average population density of 63 people per square mile with approximately 113,594 square miles of area in the state.

Arizona Historical Boundary, Census, and Statehod

Arizona was acquired from Mexico in 1848 and 1853. It was established as a territory in 1863 from New Mexico](/states/new-mexico-population/) Territory, and acquired essentially its present boundaries in 1866. Arizona was admitted as a State on February 4, 1912.
In 1850, the present-day Arizona area had no census coverage. The 1860 population is for Arizona County, New Mexico Territory, which comprised most of present-day Arizona south of the Gila River. Northern and central Arizona first had census coverage in 1870.

Arizona Population Chart

Population History

Arizona was admitted to the Union in 1912 as the final state of the lower 48. Arizona's population at statehood was just over 200,000 people, which ranked 45th of the 48 states . In the hundred years since, its population has grown rapidly, consistently posting annual growth rates of over 3%.

Since the most recent official estimate from the US Census in 2015 (6,828,065), we estimate that the population has increased by nearly 100,000. If this rate is sustained, Arizona will surpass 8 million citizens by 2026 (as projected by Arizona Office of Economic Opportunity in 2018), becoming the 12th state to reach this mark.
