2020 Census

The 2020 Decennial Census is now complete. Because funding is distributed to cities and towns based on population, when you completed your 2020 Census questionnaire, you ensured that thousands of your tax dollars are returned to your community in critical services for you and your family. These services can range from safety and health programs to parks and transportation facilities—programs that improve your quality of life. Census numbers are also used for future infrastructure planning and to guide critical business and community decisions, helping to advance local businesses and to make positive improvements in our community.

The 2020 Census results show that the resident population for the United States is 331,449,281. The Arizona resident population is 7,151,502, an increase of 11.9 percent from the 2010 Decennial Census.

The Community Profiles dashboard has been updated with a Census 2020 tab that summarizes the redistricting data.

Below are summary reports and ranking tables relevant to the MAG region from the data released to date.

The iCount2020 campaign was a regional public outreach initiative by the Maricopa Association of Governments aimed at demonstrating the importance of every single person being counted. MAG’s census outreach efforts were also featured on the U.S. Census Bureau’s website.

Data from the U.S. Census Bureau show more than 99.9 percent of Arizona households have been counted in the 2020 Census. The deadline for participation in the first-ever online census changed numerous times, but Census Bureau operations were finally completed on October 15, 2020.

What is at stake for the region? Congressional representation and $20 billion dollars in federal funding every year to Arizona for local programs in housing, education, transportation, healthcare, public safety and more.


From the U.S. Census website:

The U.S. Census counts every resident in the United States. It is mandated by Article I, Section 2 of the Constitution and takes place every 10 years. The data collected by the census determines the number of seats each state has in the U.S. House of Representatives and is also used to distribute billions in federal funds to local communities.

The 2020 Census will require counting an increasingly diverse and growing population of around 330 million people in more than 140 million housing units. To get an accurate count, the Census Bureau must build an accurate address list of every housing unit, maximize self-response to the census, and efficiently follow up with those who do not respond.

Thomas Jefferson led the first census in 1790. It had six questions: name of head of family and the number of persons in each household in five categories.

Currently we are researching four areas that focus on the major cost drivers of the census:

  • Use the Internet to increase self-response.
  • Use existing government data sources to answer census questions and reduce follow-up workload.
  • Automate operations to increase productivity and reduce staff and offices.
  • Use existing maps and address to reflect changes rather than walking every block in every neighborhood in America.

The decennial census is the largest mobilization and operation conducted in the United States and requires years of research, planning and development of methods and infrastructure to ensure an accurate and complete count.

Complete Count Committee Resources

In April 2018, Census Bureau staff conducted a series of trainings around the MAG region to help member agency staff learn about Complete Count Committees, or CCCs. These committees are formed by local governments to promote and encourage response to the 2020 Census in their communities. A CCC comprises a broad spectrum of government and community leaders who act as trusted voices to develop and implement awareness of 2020 Census to encourage responses based upon their knowledge of the local community.

On the right under "Materials" are presentations and resources from those trainings.
