District boundaries have changed over time. Therefore, senators before 2021 may not represent the same constituency as today. From 1993 until 2003, the district covered parts of north Portland, and since 2003, it has covered slightly different areas in Benton and Linn Counties, though maintaining its focus around Albany and Corvallis. The current district differs from the previous iteration by adding more land to the north and south of Corvallis in Benton County while also adding rural exurbs of Salem in southern Marion County.
