The 2010 Participant Statistical Areas Program (PSAP) allowed designated participants, following Census Bureau guidelines, to review and suggest modifications to the boundaries for block groups, census tracts, census county divisions, and census designated places for reporting data from the 2010 Census. The American Community Survey and other Census Bureau programs may also report data for these statistical areas following the 2010 Census.

The criteria for the 2010 PSAP were determined in 2007 and 2008. In late 2008 participants were identified and received their materials. All suggested modifications were due back to the Census Bureau in mid 2009.  Bi-State staff coordinated with local jurisdictions in the Region to participate in the program.
