Yuma County is diverse and that reflects positively on our economy.  We have always been a place with abundant water, sunshine and business opportunity.  Beginning with our rich history as a commercial crossing point on the Colorado River, Yuma is now a strategic crossroads for trade in North America.  


  • Between 1990 - 2000, the City of Yuma has grown 36%.
  • Classified as a Metropolitan Statistical Area, one of only three MSA's in Arizona.
  • Third fastest growing metropolitan area in the country.
  • Foreign and national business investors suddenly find Yuma on a new set of maps with higher ranking as a "place to do business."
  • A recent study, titled "Yuma County, Arizona: Growing Business At The Border," locates Yuma strategically in the Desert Pacific Region. This market area reaches Las Vegas to the North, Albuquerque and El Paso to the East, Mazatlan to the South and takes in the entire Baja peninsula North to Los Angeles, California.

  • Yuma's industry and manufacturing base has grown steadily on both sides of the border (maquiladoras included) precipitating additional trade in the Yuma-Rio Colorado region.

  • For specific economic development assistance, contact the Greater Yuma Economic Development Corporation (GYEDC) at (928) 782-7774.



  • On Interstate 8, more than 6.5 million vehicles per year (18,000 per day) pass through Yuma. At San Luis, another 2.6 million autos and 46,000 commercial vehicles cross annually.

  • Shoppers from Mexico contribute approximately $2.2 billion annually to Yuma County.

  • Yuma's annual sales continually show healthy increases compared to other parts of Arizona and the nation.

  • A Yuma business myth: As with many communities in Southwestern Arizona, Yuma's summer business seems to "die off". There is some truth to the story, but not much. In the slowest sales months of the year (June, July and August) the aggregate sales by Yuma businesses represents 22-24% of their annual sales.



  • Tax rates vary according to school district.
  • In Arizona, tax rates are stated in dollars per hundred of assessed value, rather than a mill rate like many other states. 
  • Assessed values are a fractional part of the full or limited value of the property with commercial property being assessed at an 18% assessment ratio while residential property is assessed at 10%. For example:
    • Assessed Value on a $500,000 commercial property would be $90,000.
    • Assessed Value on a $500,000 residential property would be $50,000.
