2023 National Public Opinion Reference Survey (NPORS)

NPORS is an annual, cross-sectional survey of U.S. adults. Respondents can answer by paper, online or over the phone, and they are selected using address-based sampling from the United States Postal Service’s Computerized Delivery Sequence File. The response rate to the latest NPORS was 32%, and previous years’ surveys were designed with a similarly rigorous approach.
