Survey Methodology

The Role of the Employer

The research was conducted online in the United States by The Harris Poll on behalf of the American Heart Association.

 

The Harris Poll conducted research among 2,001 employees, defined as U.S. adults age 18+ who are employed full or part time (not self-employed) with a company with 25+ employees, are enrolled in a health plan offered by their employer, and their coverage is provided by their employer.

The survey was conducted from February 26–March 12, 2026.

Data are weighted where necessary by age, gender, race/ethnicity, region, education, marital status, household size, employment, household income, as well as company size in order to bring them in line with their actual proportions in the population.

Respondents for this survey were selected from among those who have agreed to participate in Harris 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 ± 2.8 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 onresponse, error associated with question wording and response options, and post-survey weighting and adjustments.
