October-November 2022 King County Survey Methodology

Change Research surveyed 740 likely voters online for the Northwest Progressive Institute (NPI) in King County from October 28th-November 3rd, 2022.

Change used the following sources to recruit respondents:

  • targeted advertisements on Facebook and Instagram (471 respondents)
  • text messages sent, via the Switchboard platform, to cell phone numbers listed on the voter file for individuals who qualified for the survey’s sample universe, based on their voter file data (269 respondents)

Regardless of which of these sources a respondent came from, they were directed to a survey hosted on SurveyMonkey’s website.

Ads placed on social media targeted all adults. Anyone who indicated they were not registered to vote was terminated. As the survey fielded, Change Research used dynamic online sampling: adjusting ad budgets, lowering budgets for ads targeting groups that were overrepresented and raising budgets for ads targeting groups that were underrepresented, so that the final sample was roughly representative of the population across different groups. The survey was conducted in English.
