NPORS is an annual survey of U.S. adults conducted by Pew Research Center. Respondents may answer either by paper or online. They are selected using address-based sampling from the U.S. Postal Service’s Computerized Delivery Sequence File. Respondents are not required to join a survey panel. Pew Research Center uses NPORS to produce benchmark estimates for several topics, such as Americans’ political and religious affiliations.
