The Phoenix market has long been known for its explosive residential growth and through July 2025 it still ranks amongst the Top 10 single-family (15,713 permits) and multi-family (7,661 permits) housing markets, despite some sizeable year-over-year declines. And according to the most recent population data from the U.S. Census Bureau, it’s also a Top 5 market for population increases, with 311,330 new residents moving into the Valley of the Sun from 2020-2024.
Arizona has become a hotbed for construction of data centers and semiconductor plants, and one day may be home to one of the largest data center projects in the nation -- the proposed $33-billionLa Osa data center project data center campus in Eloy, AZ. Two massive semiconductor plants are being built in the Phoenix market -- the $10-billion Taiwan Semiconductor Fab 3 facility and the $7-billion Amkor plant in Amkor, AZ.
Other large Mountain MSAs are also seeing plenty of action, too. In Salt Lake City, UT, the $3-billion, 1.3-million-sq-ft Power District mixed-use project broke ground in October; a $1.3-billion renovation of the Denver Airport’s Great Hall is underway; and Las Vegas, NV, has two billion-dollar commercial projects underway – the $1.1-billion Hard Rock Hotel and the $1-billion Four Seasons Private Residences.
HOW TO USE THE DATA IN THE MARKET PLANNING GUIDE
The late Andrea Herbert, former chief editor of Electrical Wholesaling, launched the Market Planning Guide more than 40 years ago. She won several national editorial awards for her efforts with the Market Planning Guide, including the Jesse H. Neal Award, the business press’ highest honor.
She wanted the Market Planning Guide to be a practical tool for salespeople and managers at distributors, manufacturers and independent manufacturers’ reps, and her thoughts on how to use it still ring true today:
• Determine market share & penetration.
• Evaluate branch performance and decide which local market areas may support new branches.
• Determine the areas with the greatest sales potential so you can concentrate your salespeople’s efforts in the most productive directions.
• Keep on top of changes in the market area (new residential development, large construction projects in the pipeline & population shifts).
• Direct advertising and promotion to the places where it will have the most impact.
• Explain to suppliers what they can expect from you in the way of market coverage.
• Verify or challenge what suppliers expect from you in sales.
• Set sales quotas for salespeople, territories or product lines.
• Calculate the number of salespeople needed to cover an area.
• Compare how well salespeople in different territories are doing with the same product on the basis of market potential.
• Back up intuition.
OTHER REALLY USEFUL DATA
In addition to breaking out our national and regional sales potential estimates, the 2026 Market Planning Guide also offers some other great local data that will help offer a clearer picture of the electrical opportunities available: electrical contractor and industrial employment, population growth, construction projects worth at least $100 million in total construction value and building permits.
Electrical Contractor Employment Data
You can use use this employment data with EW's sales-per-employee estimates for electrical contractors of $78,775 per employee to develop contractor sales potential estimates at the local and state level.
You can use use this employment data with EW's sales-per-employee estimates of $2,650 per employee to develop industrial sales potential estimates at the local and state level.
Population Change (2020-2024)
Following population trends is a quick-and-easy way of gauging a market’s local economy. If a market is gaining or losing residents, it obviously affects the tax base, enrollments counts and schools and the need for additional construction for service industries. In our presentation of the U.S. Census Dept.’s 2023 data at the MSA and state level, we map out new-residents-by-day data, which is calculated with the number of folks moving into or out of a local market. It’s a simple calculation that highlights population growth in a fun and easy-to-view manner.
Construction Projects
Electrical work typically accounts for roughly 10% of total construction value of a project, and the construction projects highlighted here offer a sense of the project mix available in a given state or region. Our construction project data was gathered through Oct. 2025. Electrical Marketing newsletter updates its construction project database each quarter, and those updates can be downloaded in a spreadsheet as part of a $99 subscription. Our decision to only include the projects we find of $100 million of more in total contract value is based totally on the bandwidth of the EW staff; we realize that many smaller projects can be even more profitable than larger jobs.
Building Permits
Available monthly from the U.S. Census Bureau on an MSA, state and national level, building permits are a leading indicator of future residential construction because homebuilders typically don’t invest in a permit until they are serious about breaking ground. Permit data is also an early indicator of future nonresidential construction in a local market, because once residential developments go in, the constructions of stores, light commercial and other projects typically follows.

He showed an early interest in electricity, when as a youth he had an idea for a hot dog cooker. Unfortunately, the first crude prototype malfunctioned and the arc nearly blew him out of his parents' basement.
