Household Incomes on the Rise The region’s median household income has steadily increased since 2010, and was 10 percent higher than both the state and the nation in 2023. This rise is partly due to a growing number of households with multiple workers, which reached 39 percent in 2023, up from 32 percent in 2010. In 2023, the median household income in the MAG region was $85,700. The median household income nationwide was $77,700. Household Income Data 2.

The project will add travel lanes, build new direct freeway-to-freeway ramps, and improve mobility in the fast-growing North Valley. MAG planned this project as the first Prop 479 transportation project, which Maricopa County voters approved in 2024. Read more about the project on ADOT's website.

Help Shape the Future of Travel in the North Valley The North Valley Corridor Study focuses on improving safety, mobility and regional connectivity along a 15-mile stretch of I-17 and Loop 101, one of the fastest-growing and most heavily traveled areas in the MAG region. Through data analysis, community input and collaboration with partner agencies, the study identifies potential improvements to freeways, interchanges and arterials to address congestion today while planning for future growth.
