From October 9 to October 13, 2024, Portland polling firm DHM Research conducted a survey of registered voters in the Portland metropolitan area on behalf of The Oregonian/OregonLive.
The survey involved 600 voters, half of them from the city of Portland, matched to reflect age, gender, education, political affiliation, and race of the area’s adult population. The total results for the Portland metropolitan area were statistically weighted proportionally to the populations of Clackamas, Multnomah, and Washington counties.
Respondents completed the survey via live interview calls, including both landline and cell phones, and online via a link sent via text message. Half of the respondents were interviewed by a live interviewer and 50% completed the survey online. Various quality control measures were employed when collecting responses, including pretesting and validation of the questionnaire.
The poll had a margin of error of plus or minus 4 percentage points. Results specific to the city of Portland have a margin of error of plus or minus 5.7 percentage points.
