2020 Census Participant Statistical Areas Program (PSAP)
The 2020 Census Participant Statistical Areas Program (PSAP) allows local governments, following Census Bureau guidelines, to review and update the boundaries for Census tracts, Census block groups, Census Designated Places, and, where applicable, Census County Divisions for the 2020 Census. The updated statistical areas will be used by the Census Bureau to report data from the 2020 Decennial Census, American Community Survey, and, as appropriate, other censuses and surveys.
The Des Moines Area Metropolitan Planning Organization (MPO) is serving as the 2020 Census PSAP primary participant for the counties of Boone, Dallas, Jasper, Marion, Polk, Story and Warren in the region. The MPO will coordinate the edits to Census geography boundaries with input from local governments and entities and submit final boundary plans for each county to the Census Bureau in late spring 2019. The Census Bureau will review the edits and determine the final delineations to be validated in 2020.
To stay informed about the 2020 Census PSAP process, please contact the MPO staff 515-334-0075.
