When created in 1983, the district was an inland district focused around the
Willamette Valley, and consisted of all of
Clackamas and
Marion counties, as well as small parts of the counties of
Benton,
Linn, and
Polk. In 1993, the district gained a large coastal portion from the
1st district, gaining all of
Tillamook and
Lincoln counties as well as the rest of Polk, whilst part of Clackamas County was lost to the
3rd district. In the 2003 and 2013 redistrictings, the changes were only minor, as the district gained a small portion of
Multnomah County from the 3rd district in 2003 but lost it again in 2013, while it lost a portion of northern Clackamas County to the 3rd district in both 2003 and 2013. In the 2023 redistricting, the district underwent major boundary changes, as it gained all of Linn County, some of Multnomah and Clackamas counties, and parts of
Deschutes County including
Bend, but it lost the entire coastal section it had gained in 1993 as well as the area in Polk and Benton counties to the 1st,
4th, and
6th districts. Parts of western Marion County, including the city of
Salem, were also lost to the new 6th district. File:United States Congressional Districts in Oregon (metro highlight), 1983 – 1992.tif|
