Why Arizona matters to US business
Arizona's recent business story is dominated by the intersection of population growth and industrial investment. Greater Phoenix has become a major semiconductor manufacturing centre, led by TSMC, Intel and a growing supplier ecosystem, while aerospace and defence remain longstanding strengths around Phoenix and Tucson.
The state also benefits from migration from California and other western markets. That has expanded housing, consumer services, healthcare and logistics, although rapid growth has made water, power and infrastructure planning more important to large projects.
Major industries in Arizona
Semiconductors
Greater Phoenix is becoming one of the country's most important chip-manufacturing hubs. TSMC's fabs, Intel's long-standing presence and supplier investment are building a deeper semiconductor ecosystem around fabrication, packaging, materials and equipment.
Aerospace And Defence
Arizona has a large aerospace and defence cluster spanning missiles, aircraft systems, space technology and military installations, with major activity in both Phoenix and Tucson.
Construction And Real Estate
Fast population growth has kept construction and real estate unusually important, from housing to industrial parks and large infrastructure projects.
Business Services
Phoenix has developed into a large back-office, financial-services and corporate-operations market as companies seek lower-cost western US locations.
Logistics
Arizona's position between California, Texas and Mexico supports warehousing, distribution and cross-border trade, particularly around Phoenix and the southern border.

Phoenix
Semiconductors, finance, business services, healthcare, construction and logistics make Phoenix one of the fastest-growing large business markets in the West.
Tucson
Aerospace, defence, optics, research and the University of Arizona give Tucson a more specialised technical economy.
Mesa and Chandler
These East Valley cities are central to the semiconductor, aerospace and advanced-manufacturing buildout around Greater Phoenix.

What businesses are investing in now
Semiconductor fabs
Large fabrication projects are pulling equipment makers, materials suppliers and engineering firms into Greater Phoenix.
Power and water infrastructure
Industrial growth is increasing the importance of power supply, water reuse and long-term utility planning.
Advanced manufacturing
Aerospace, electronics and battery-related investment are broadening the state's manufacturing base beyond construction-led growth.
Employment and workforce
Arizona's population growth has expanded the labour pool, but semiconductor and aerospace employers compete for specialised engineers, technicians and skilled trades.
Community colleges and employer training programmes have become important parts of the state's effort to convert population growth into industrial capability.
Trade and exports
Arizona's trade relationships are increasingly tied to semiconductors, electronics, aerospace products and cross-border commerce with Mexico.
The state's manufacturing growth makes imported equipment and components more important too, so supply-chain resilience matters alongside export growth.
ACR view
Arizona is one of the clearest examples of industrial policy becoming local economic geography. The semiconductor buildout is large enough to change Phoenix's labour market, utility planning and supplier base. The upside is a more advanced industrial economy; the constraint is whether water, power and skilled labour can scale with it.

Florida business profile
Florida is no longer well described as a tourism economy alone. Migration has expanded construction, healthcare, finance and professional services, while Miami, Tampa, Orlando and Jacksonville have developed very different business specialisms.
Core sectors: tourism and hospitality, financial and professional services, aerospace
Ohio business profile
Ohio's strength is breadth. Columbus is growing as a finance, technology and logistics centre, while Cleveland, Cincinnati and Dayton anchor healthcare, consumer products, manufacturing and aerospace supply chains.
Core sectors: advanced manufacturing, financial services, healthcare
Alabama business profile
Alabama's modern business story is increasingly split between Huntsville's aerospace and defence economy, Birmingham's services base and a vehicle-manufacturing corridor tied into the wider Southeast supply chain.
Core sectors: automotive manufacturing, aerospace and defence, metals and advanced manufacturing
Delaware business profile
Delaware's population is small, but its role in US corporate law makes it nationally important. The state's business identity is shaped as much by incorporation and financial services as by the companies physically operating there.
Core sectors: financial services, chemicals and materials, life sciences
