There are 4,395 people per square mile in the Phoenix-Mesa-Scottsdale metro area, lower than the national population density of 6,321 Americans per square mile across all U.S. metro areas. Phoenix also has the highest population density of any Arizona metro area.

Population density can have a meaningful impact on home prices in an area. There tends to be less demand for available real estate in sparsely populated areas, and home prices are often lower as a result. In Phoenix, a typical home is worth $219,100, more than the national median home value of $194,500. Phoenix has the second highest median home value of any metro area in the state.

Dense metropolitan areas are often the most congested, with the average worker spending up to 38 minutes commuting to work in some cities. The average commute in Phoenix lasts 25.4 minutes, roughly similar to the average commute time for Arizona as a whole of 25.1 minutes and the highest of any metro area in the state.

One of the most effective deterrents to crime is other people. In more rural cities there is often fewer people and less streetlight to act as natural surveillance that can in some cases prevent petty crime. In the Phoenix-Mesa-Scottsdale metro area, there were 2,824 property crimes per 100,000 people in 2015, higher than the national property crime rate of 2,487 incidents per 100,000 Americans and lower than the statewide rate of 3,033 property crimes reported per 100,000 residents. Phoenix has the fourth lowest property crime rate and second highest violent crime rate in Arizona.
