The research was conducted online in the United States by The Harris Poll on behalf of Nationwide among 1,324 Americans ages 29+ with household income of $75K+. The survey was conducted March 17 – Apr. 7, 2025.
Data are weighted where necessary by age by gender, race/ethnicity, region, education, marital status, household size, household income, and political party affiliation to bring them in line with their actual proportions in the population. Data for Black and Hispanic were also weighted by employment. Respondents for this survey were selected from among those who have agreed to participate in our surveys.
The sampling precision of Harris online polls is measured by using a Bayesian credible interval. For this study, the sample data is accurate to within +/- 3.8 percentage points using a 95% confidence level. This credible interval will be wider among subsets of the surveyed population of interest.
All sample surveys and polls, whether or not they use probability sampling, are subject to other multiple sources of error which are most often not possible to quantify or estimate, including, but not limited to coverage error, error associated with nonresponse, error associated with question wording and response options, and post-survey weighting and adjustments.
