As of April 1, 2020, the Phoenix–Mesa CSA had a population of 4,899,104, making it the fourteenth-most populous in the nation.
Metropolitan Statistical Area
The Phoenix Metropolitan Area comprises Maricopa County (2020 population: 4,420,568) and Pinal County (2020 population: 425,264). It is officially designated by the US Census Bureau as the Phoenix–Mesa–Chandler, AZ Metropolitan Statistical Area. The total population for metropolitan Phoenix at the 2020 Census was 4,845,832.
The Phoenix Metropolitan Area is hundreds of miles away from any other metropolitan area of similar population size. For instance, the closest metropolitan area with almost the same population size is the
Riverside-San Bernardino-Ontario, CA Metro Area, which is 300 miles away.
Demographics

As of the 2010 census, there were 4,192,887 people, 1,537,137 households, and 1,024,971 families residing within the MSA. The racial makeup of the MSA was 73.0%

Geography
As of 2020, the Phoenix Metropolitan area consists of Maricopa and Pinal counties, comprising a total area of about 14,600 square miles. Because of the size of counties in Arizona, even though Maricopa and Pinal counties together contain nearly 4.9 million people, most of the area is uninhabited, which gives the MSA an extremely low density compared to other major MSAs in the nation.
The average elevation in the city itself is about , with the highest point being in South Mountain Park Preserve .The highest point in the two county area is in the Four Peaks mountain range.
Climate
Metropolitan Phoenix is notable for its warm, desert climate. On average, the area receives about 9 inches of rain annually, with less than 1 inch of snow every decade. In total, the region will see about 32 days of measurable precipitation each year. The MSA is one of the sunniest major metropolitan areas, receiving 295 days of sunshine, compared to the national average of 205. The average July high is about 104 °F (40 °C), with the average January low being about 36 °F (3 °C), still above freezing. Bestplaces gives Metropolitan Phoenix a comfort index of 44/100, which is also the national average.
Below is a chart showing climate data collected from
Sky Harbor Airport. Due to the vast area covered by the MSA, climates vary throughout the valley.
Economy
Metropolitan Phoenix has historically been the center of the state's economy. As with the state of Arizona, the area relied on the 5 C's (copper, cattle, climate, citrus, and cotton) for its economic growth and expansion. However, after World War II, the area entered the manufacturing industry, which spurred the growth of what would eventually be one of the largest urban areas in the nation. Currently, the two largest industries are manufacturing and tourism. About 10 million people visit from other states and Canada each year, due to the area's mild winters and long, sunny days. The technology and service industries currently account for almost 77% of total employment in the region. As well as a strong tourism industry, the Phoenix area has a significant business sector. Several Fortune 500 and Fortune 1000 companies have their international headquarters in the area, including

The Metropolitan Area ranks 5th in the nation in economic growth, which is a major comeback from the recession. The unemployment rate of the area is 5.3%, lower than the national rate of 6.3%. It also has slightly higher recent job growth (2.0% compared to 1.2%) and higher projected job growth (38.7% compared to 36.1%). Although the area has significantly higher sales tax rates compared with the nation as a whole (8.3% to 6.0%), income tax rates are lower than the national average (3.4% to 4.7%). The largest occupation by population is in the office/administrative sector, comprising more than a quarter of all jobs in the region.
Infrastructure
Transportation
Freeways and expressways

The Phoenix Metropolitan Area is served by several controlled-access freeways, including:
*
*
*
*
*
*
*
*
New freeways are planned in the future, either through upgrades of existing roads such as
SR 74,
SR 85, and
Northern Parkway; or through the construction of new freeways where no road existed before such as
SR 24 and
SR 30.
Arterial roads

Most of the arterial roads in the Phoenix metropolitan area are laid out on a regular
grid, following the
section lines established in the
Public Land Survey System
The Public Land Survey System (PLSS) is the surveying method developed and used in the United States to plat, or divide, real property for sale and settling. Also known as the Rectangular Survey System, it was created by the Land Ordinance of 17 ...
. As a result, arterial roads in cities that had once been geographically separate may have been given different names while occupying the same section line. When these roads were extended to accommodate the growth in the area they eventually merged into a single road while the previous segments retained their existing names. This results in several cases of a road abruptly changing names; for example, Dunlap Avenue in Phoenix becomes Olive Avenue west of 43rd Avenue, in Glendale.
Another quirk of a grid system based upon the Public Land Survey System is due to the occasional corrections in the grid caused by the
curvature of the Earth
Spherical Earth or Earth's curvature refers to the approximation of the figure of the Earth as a sphere. The earliest documented mention of the concept dates from around the 5th century BC, when it appears in the writings of Greek philosophers. ...
. This results in arterial roadways deviating slightly from a straight line, as can be seen in many locations where roads abruptly curve either just north or just south of Baseline Road to follow a new section line.
The majority of the cities in the metropolitan area, as well as unincorporated areas in Maricopa County, observe the
addressing system employed by the city of Phoenix. A number of cities, however, retain their own addressing systems with differing reference points, creating the potential for multiple instances of a house number being found on the same named road.
In terms of numbering systems, some roads that continue through multiple cities will switch numbering conventions several times. Broadway Road, for example, starts and stops multiple times, passing through Goodyear, Avondale, Phoenix, Tempe, Mesa, and Apache Junction, each with their own reference point for address numbering. Though the street does not curve, the direction changes from west to east in each city and back again when moving from one city to the next, causing considerable overlap in numbers.
Street numbering systems
Most communities in Maricopa County use the Phoenix-County numbering system, with the point of origin at Central Avenue and Washington Street. In the Phoenix-County system, north-south numbered roads labeled "avenue", "drive", and "lane" are West of Central Avenue, while those labeled "street", "place" and "way" are east of Central Avenue. Starting with 579th Avenue in the west near Tonopah the avenues count down with approximately 8 numbers per mile to 19th Avenue and count up again to from 16th Street to 228th Street near Queen Creek in the east. They go, in order from west to east (although not all necessarily exist):
* 2nd Avenue – 1st Dale – 1st Glen – 1st Lane – 1st Drive – 1st Avenue
* Central Avenue
* 1st Street – 1st Place – 1st Way – 1st Terrace – 1st Run – 2nd Street
This has been a source of confusion for a few newcomers, who might end up, for example, at 91st ''Avenue'' and Thunderbird Road, when in fact they intended to go to 91st ''Street'' and Thunderbird Road, between 30 minutes and an hour away from one another depending on traffic.
One beneficial quality of this arrangement for unfamiliar travelers is that the major north-south
arterial road

s are rarely similarly named; the "avenue" arterials in the West Valley are all odd-numbered and the "street" arterials in the East Valley are even-numbered, with the exception of 7th Ave. & 7th St., both being major roadways running parallel and each one-half mile from Central Ave.
Communities in Maricopa County that have their own street numbering systems include:
Additional confusion can be encountered in Mesa in its urban core, with east-west numbered avenues and drives counting down from 11th Avenue north towards Main Street), and numbered streets and places counting down from 11th Place south towards Main Street. Then, in the eastern part of the city, north-south streets and places count up from 22nd St east of Gilbert Rd, to 112th Street on the Apache Junction border. Numerous trailer parks inside the city limits run their own contradictory variations of the numbered street system.
Most communities in Pinal County use the Pinal County street numbering system, whose point of origin is at
SR 287 and 11 Mile Corner Road (the intersection of which is known as "11 Mile Corner"). Exceptions include:
Apache Junction continues Mesa's convention of numbered north-south street names by having the sequence continue east from 112th St while simultaneously having east-west numbered avenues south of Apache Trail and east-west numbered streets north of Apache Trail.
Traffic safety
In terms of safety, the Phoenix–Mesa–Chandler, AZ metropolitan area has been ranked 16th most dangerous in the USA, based on its Pedestrian Danger Index, computed on the share of local commuters who walk to work and the most recent data on pedestrian deaths as found in a 2016 report released by
Smart Growth America.

Many expansions to the METRO system are currently in the early planning stages, and others are under construction. The Central Mesa extension project, which extends the Main Street line miles from Sycamore to Mesa Drive in Downtown Mesa, finished construction and opened on August 22, 2015. The Northwest rail project opened March 2016. The project extended the 19th Avenue track from its former terminus at Montebello Ave to Dunlap Avenue, 3 miles north. Many more extensions are funded, with further projects being studied for feasibility.
