Arizona Economy: Sun, Semiconductors, and the Sun-Belt Boom

Arizona has one of the fastest-growing large state economies in the United States, usually ranked in the top twenty by GDP — the dollar value of everything a place makes and sells in a year. The Arizona economy used to be defined by tourism, retirees, and copper mining; today it is led by semiconductor manufacturing, healthcare, and a steady inflow of new residents and corporate relocations.

This is a plain-English tour. For the national picture, see The State of the U.S. Economy and the Economy hub.

How big is the Arizona economy?

For example, recent state GDP for Arizona has run around $530 billion, according to the Bureau of Economic Analysis. Population is roughly 7.5 million, per the U.S. Census Bureau. The Phoenix metro area accounts for the majority of the state's population and an even larger share of its economic output, with Tucson as the second-largest center.

The biggest industries

Arizona's economy is broadening fast, but a few sectors do most of the work:

• Semiconductor manufacturing — major chip plants from Intel, TSMC, and others are being built or expanded in the Phoenix area, supported by federal industrial policy.
• Healthcare — major hospital systems serve a large and growing senior population.
• Tourism and hospitality — the Grand Canyon, Sedona, Scottsdale, and the wider desert landscape drive a major travel sector.
• Construction and real estate — fast population growth keeps demand for new housing and commercial space high, especially in the Phoenix metro.
• Aerospace and defense — Tucson hosts large Raytheon operations, and Luke Air Force Base is a major fighter-pilot training site.
• Mining — Arizona is the largest U.S. producer of copper.
• Agriculture — cotton, lettuce, and dairy are still meaningful, especially in the irrigated parts of central and southern Arizona.

Jobs and wages

Arizona labor data is published by the Arizona Department of Economic Security, with national-level numbers from the Bureau of Labor Statistics. For example, Arizona's unemployment rate has typically run close to or a bit above the national average, with the Phoenix metro tracking the state's overall picture.

Arizona's minimum wage is set by a state law that adjusts each year for inflation, keeping it well above the federal floor of $7.25 per hour. Flagstaff sets a higher local minimum.

Taxes in Arizona

Arizona has a flat state income tax with a low rate, after a multi-year transition from a graduated system. Arizona cities do not charge a separate local income tax.

The state sales tax rate (technically a "transaction privilege tax") is 5.6%, with cities and counties adding their own pieces, putting the combined rate in most places between 7% and 9%.

State tax forms and rules live at the Arizona Department of Revenue. You can read more about how sales tax works in our glossary.

Cost of living

Cost of living in Arizona has historically run a bit below the national average, but housing in the Phoenix and Tucson metros has risen sharply since 2020. Smaller Arizona cities and rural areas remain more affordable. Resort towns like Sedona and Flagstaff are well above average, especially for housing.

The federal government tracks region-specific Consumer Price Index data through the BLS West region, and HUD publishes Fair Market Rents for every county at HUD User.

Sun, semiconductors, and the Sun-Belt boom

The biggest recent shift in Arizona's economy is the rapid growth of semiconductor manufacturing in the Phoenix area. Massive Intel and TSMC plants either operate or are being built outside Phoenix, supported by the federal CHIPS Act. That has pulled in billions of dollars of investment, thousands of high-wage jobs, and a long supply chain of equipment and material suppliers. On top of that, Arizona keeps adding residents from California and other higher-cost states, which fuels demand for housing, healthcare, and services.

How does the Arizona economy fit into the national picture?

Arizona is a model Sun Belt growth story: fast-growing population, lower cost base than California, and a flat low income tax. The state's economy is unusually exposed to housing — when housing demand cools, construction and related sectors slow quickly. Federal industrial policy has shifted Arizona toward higher-paying advanced manufacturing jobs in addition to its traditional service-sector base.

Water and the desert economy

One thing that is impossible to ignore in Arizona is water. Most of the Phoenix and Tucson metros sit in a desert and depend on a combination of the Colorado River, in-state rivers, and groundwater. Long-running drought conditions and ongoing negotiations over Colorado River water have direct effects on agriculture, new housing approvals, and even where new factories can be built. Federal data on water and drought lives at the U.S. Geological Survey and the Bureau of Reclamation. Water policy is now part of any serious conversation about Arizona's long-term economic growth.
