Statement of Methodology

This survey of 1,000 registered voters was conducted between January 7-January 11, 2025, and is based on live telephone interviews of adults 18 years of age or older, residing in all 50 states and the District of Columbia. Quota and demographic information – including region, gender, education, race, and age – were determined from American Community Survey Census and November 2024 exit poll data. Samples of both cell phones and standard landlines were called using a probability-proportionate-to-size method, which means that the phone numbers assigned to each state were proportional to the number of registered voters in each state. States were grouped into four general regions. Surveys were administered in English and Spanish. The margin of sampling error for results based on the total sample is +/-3.1 percentage points. Error margins increase for smaller subgroups in the cross-tabulation document above. All surveys may be subject to other sources of error, including but not limited to coverage error and measurement error.
