The Yale and AP-NORC Center survey of 1,578 adults was conducted online Nov. 20-Dec. 1, using a sample drawn from GfK’s probability-based KnowledgePanel, which is designed to be representative of the U.S. population. The margin of sampling error for all respondents is plus or minus 2.9 percentage points.
Respondents were first selected randomly using phone or mail survey methods and later interviewed online. People selected for KnowledgePanel who didn’t otherwise have access to the Internet were provided access at no cost to them.
Funding for the survey was provided by the Yale School of Forestry & Environmental Studies.
