2010 Census Count Question Resolution (CQR) Program

The deadline to submit a challenge to the 2010 Census Count Question Resolution Program was June 1, 2013.

The Census Bureau established the 2010 Census Count Question Resolution (CQR) Program by which State, local and Tribal area elected officials could challenge their jurisdiction's 2010 Census counts. On June 1, 2011, the Count Question Resolution (CQR) Program began accepting 2010 Census challenge submissions. All challenges had to be received by the Census Bureau no later than June 1, 2013.

The U.S. Census Bureau partnered with state, local and tribal governments across the nation to help ensure a complete and accurate count in the 2010 Census. The Census Bureau's goal was to count everyone once, only once, and in the right place. There are historically a small percentage of cases where a wrong geographic boundary or coding of a housing unit was used to produce the official census population and housing counts for a local area. There may also be processing errors. The Census Bureau does not collect any additional data during the challenge process.

If a challenge results in a change, the Census Bureau issues official revised counts to the affected governments. These changes can be used by the governments for future programs that require official 2010 Census data. They are also used to calculate subsequent population estimates for that community.

IT'S A FACT: Following the 2000 Census, potential count problems were identified for 1,180 out of 39,000 jurisdictions — less than 3 percent of all governmental jurisdictions across the nation. The final 2000 CQR corrections resulted in a net gain in population of about 2,700 people. This amounts to about 1/1000th of one percent of the nation's population of 281 million people counted in the 2000 Census.
