Colorado Independent Redistricting Commissions Staff Preliminary Data Disclaimer
The sudden worldwide pandemic of the Coronavirus Disease 2019 (COVID-19) in 2020 resulted in an unprecedented and significant disruption in the conduct of the federal 2020 decennial census. The U.S. Census Bureau was originally scheduled to release the redistricting data to the states by April 1, 2021, but due to the delays caused by the pandemic, the Census Bureau has announced they plan to release the redistricting data in a “legacy format” by August 16, 2021 and an equivalent “user-friendly format” by September 30, 2021.

Both the Congressional and Legislative commissions have found that waiting until mid-August for the earliest set of census data to begin creating the preliminary redistricting plans will likely result in the commissions missing their constitutional deadlines. As a result, both commissions decided to move forward with a “preliminary” dataset using third party sources in order to create the nonpartisan “preliminary plans” required under the Colorado Constitution. The commissions believe that this preliminary dataset is sufficient to create the preliminary plans required by the Colorado Constitution. The commissions are releasing this dataset only for the purpose of disclosing how the preliminary plans were created. The commissions do not anticipate using this dataset for any other purpose.
