Participants enrollment in the survey. A total of 2,010 participants were invited to participate of which 938 were eligible to participate. Of these 938, 672 participants (72%) completed the survey. Eligible for survey: Participants who were 18 years and older, could read English, and had a working CloudResearch account. Quota overfill: Eligible participants who were unable to participate because the strata they were associated with was already adequately represented. As the survey was meant to be representative of the U.S. population, if certain strata reached its quota based on our sample size, other participants in that strata became ineligible to participate in the survey. Eligible to participate: Eligible participants who could complete the survey after removing ineligible and quota overfill participants from the invited participants.
