TOPLINE AND METHODOLOGY About the Study This Axios-Ipsos Two Americas Survey was conducted March 10 to March 13, 2023 by Ipsos using our KnowledgePanel®. This poll is based on a nationally representative probability sample of 1,018 adults ages 18+. The survey was conducted using KnowledgePanel, the most well-established online probability- based panel that is representative of the adult US population. Our recruitment process employs a scientifically developed addressed-based sampling methodology using the latest Delivery Sequence File of the USPS – a database with full coverage of all delivery points in the US. Households are randomly sampled from all available households in the US. All persons in selected households are invited to join and participate in KnowledgePanel. Ipsos provides selected households that do not already have internet access a tablet and internet connection at no cost to them. Those who join the panel and who are selected to participate in a survey are sent a unique password-protected log-in used to complete surveys online. As a result of our recruitment and sampling methods, samples from KnowledgePanel cover all households regardless of their phone or internet status and findings can be reported with a margin of sampling error and projected to the general population. The study was conducted in English and Spanish. The data were weighted to adjust for gender by age, race/ethnicity, education, Census region, metropolitan status, household income, and party identification. The demographic benchmarks came from the 2022 March supplement of the U.S. Census Bureau’s Current Population Survey (CPS). Party ID benchmarks are from recent ABC News/Washington Post telephone polls. The weighting categories were as follows: • Gender (Male, Female) by Age (18–29, 30–44, 45–59, and 60+) • Race/Hispanic Ethnicity (White Non-Hispanic, Black Non-Hispanic, Other or 2+ Races Non- Hispanic, Hispanic) • Education (Less than High School graduate, High School graduate, Some College, Bachelor’s and beyond) • Census Region (Northeast, Midwest, South, West) • Metropolitan status (Metro, non-Metro) • Household Income (Under $25,000, $25,000-$49,999, $50,000-$74,999, $75,000-$99,999, $100,000-$149,999, $150,000+) • Party ID (Democrat, Republican, Independent, Something else) The margin of sampling error is plus or minus 3.3 percentage points at the 95% confidence level, for results based on the entire sample of adults. The margin of sampling error takes into account the design effect, which was 1.17. The margin of sampling error is higher and varies for results based on sub-samples. In our reporting of the findings, percentage points are rounded off to the nearest whole number. As a result, percentages in a given table column may total slightly higher or lower than 100%. In questions that permit multiple responses, columns may total substantially more than 100%, depending on the number of different responses offered by each respondent. 2020 K Street, NW, Suite 410 Contact: Chris Jackson Washington DC 20006 Senior Vice President, US, Public Affairs, Ipsos +1 202 463-7300 Email: [email protected] Tel: +1 202 420-2025
