Where Are Arizona’s Highest, Lowest Census Response Rates?

Wednesday, April 1, is Census Day. That’s the reference date used for the 2020 Census. That means you include everyone living in your home on April 1 when you fill out the form, but you don’t have to wait to  complete the census.

Data posted on March 28, 2020, showed the national self-response rate was 31.6%. Arizona’s statewide census response rate was 30.9% and responses vary widely among counties. At 34.1%, Yavapai County had the highest rate followed by Maricopa and Pima Counties. The lowest response rate was reported in northeast Arizona — in Apache County — at 1.2%.

Here’s a rate breakdown of all Arizona counties provided by the U.S. Census as of March 27, 2020.

  • Arizona 30.9%
  • Apache 1.2%
  • Cochise 28.1%
  • Coconino 17.8%
  • Gila 19.2%
  • Graham 24.9%
  • Greenlee 13.7%
  • La Paz 4.0%
  • Maricopa 33.5%
  • Mohave 31.0%
  • Navajo 10.4%
  • Pima 33.0%
  • Pinal 28.9%
  • Santa Cruz 17.0%
  • Yavapai 34.1%
  • Yuma 20.9%

The Constitution mandates a census every 10 years to count every person living in the U.S., regardless of citizenship status, race or age. For the first time, people can complete the census online using a unique code mailed to their address in March 2020. There’s also an option to participate by email or phone.
The state receives $2,959 in federal funding for each person counted in Arizona. Based on an analysis of funding through 55 federal programs, Andrew Reamer of George Washington University found  Arizona received $20,550,087,125 in 2016 based on data from the 2010 census. That averages $3,214.96 per resident.

Census data are also used to calculate seats in the U.S. House of Representatives. Thanks to population growth, Arizona is expected to gain one congressional seat.
