Important Results for Arizona from the 2010 Census
By Maile L. Nadelhoffer, Valorie Rice, and Marshall Vest
On March 10, 2011, Arizona got its first look at county and city level information from the 2010 Census when redistricting data were released for our state. Since Arizona gained a house seat as a result of the new Census count, the independent redistricting commission will use these data to decide where the new legislative district will be. This data release included total population, population over the age of 18, race and Hispanic origin, the number of housing units and occupancy status for all areas down to the block level. Demographic profiles for counties and places containing more detailed age data will be released in May and more data will be made available this summer.
- Most Arizona counties grew by double digit percentages over the decade. Pinal County grew the most, experiencing a 109% gain between 2000 and 2010. Greenlee is still the smallest county and was the only one to lose population, decreasing by 1.3% over the ten years.
- Hispanics now account for 29.6% of Arizona’s population. That’s up from 25.3% a decade ago. Hispanics account for 29.6% of residents in Maricopa County, 34.6% in Pima, and 28.5% in Pinal. The highest and lowest proportions were in Santa Cruz (82.8%) and Apache (5.8%). Read more.

On December 21, 2010, U.S. Census Bureau released the resident population count for the United States as of April 1, 2010, as well as, the state population counts and congressional apportionment numbers based on the just-finished decennial census.
