Redistricting Information

Redistricting after the 2020 Census

Redistricting from the 2020 Census will begin in 2021 as Federal, State and local Districts redistrict electoral boundaries based on new 2020 Census population numbers.

Metro will redraw Metro Council zones in spring of 2021. Multnomah County will redraw Council boundaries in summer 2021. The Oregon Legislature will act to draw Congressional and State legislative boundaries during the 2021 Legislative session. Other local jurisdictions will act to redraw electoral boundaries in 2021 and 2022. 

Multnomah County will develop new precinct boundaries in 2021 and 2022, by legislative district, based on the new electoral boundaries, following state statute. Precincts are administrative in nature because Oregon is a vote by mail state. One of the goals in developing precincts is to minimize the number of precincts and splits which create ballot styles for each election. Currently, there are 113 precincts and 255 split precincts in Multnomah County.

Historical Information on Redistricting and Precincts

After the 2010 Census, 2011 and 2012 were transitional years for redistricting of political boundaries. In 2016, some precincts were consolidated due to a change in the cap of registered voters allowed per precinct.

Links below to older precinct maps and precinct changes. Districts and precincts change every ten years after the Decennial Census. Precincts may change during the ten year cycle as district boundaries change or the number of voters in a precinct change.
