Want to know which are the largest cities in Arizona? Here’s an updated list of the biggest and most populated cities in Arizona by size and population in 2020.

Arizona is the 6th largest state in the US by area and the 14th most populated state in the United States. It’s located in the southwest and has a population of 7,171,646 people. There are 91 municipalities in total, but only 10 cities are home to more than 100,000 residents. 


Phoenix is the largest city in Arizona, both in terms of size and population. It is home to 1,490,758 residents and is currently ranked as one of the most populated cities in the U.S. Phoenix serves as the State Capital and makes up the majority of the Phoenix Metropolitan Area. 

It was incorporated in 1881, although it was settled already in 1867. Additionally, it’s the seat of Maricopa County and the city covers an area of 516.70 Square miles.

The Hohokam People have lived in the area for over 2000 years and they created the foundation of the city with irrigation canals that made the soil arable. Much of the city’s economy revolves around the 5Cs, which are cattle, copper, climate, cotton, and citrus.

It’s a major transportation hub for the Union Pacific Railroad’s Sunset Route but it also attracts some 3.5 million visitors annually. The mild winters and sunny climate year-round are some of the biggest factors behind tourism, and a large number of resorts and hotels.
