The Census Bureau has released the 2020 Decennial Census Statistical Geography for Colorado. This includes official 2020 Census Tracts, Block Groups, and Census Blocks. These are the geographies to be used for redistricting and subsequent 2020 demographic data releases. Note: these are geographies only, demographic data from the 2020 Census are not yet available. It has been delayed due to COVID-19.
