Redistricting Information

After the 2010 Census, 2011 and 2012 were transitional years for redistricting of political boundaries. Political boundaries that effect voters in Multnomah County include US Congress, State Senate, State House, Metro Council, Multnomah County Commissioners, PCC board, MHCC board, ESD boards, Rockwood and Interlachen PUD boards. 

In 2016, some precincts were consolidated due to a change in the cap of registered voters allowed per precinct.

After the 2020 Census, redistricting will begin in 2021 through 2022. Metro will redraw Metro Council zones in spring 2021 and the Oregon Legislature will act to draw new Congressional and Legislative boundaries during 2021. Other Special Districts with elected zones will redistrict in 2021 and 2022. Precincts will be developed based on these new boundaries for the elected districts. 

Below is information on the last redistricting process after the 2010 Census
