Design: The Center for American Progress conducted a June 2020 survey of 1,528 LGBTQ-identifying individuals with assistance from NORC at the University of Chicago, using their AmeriSpeak panel. A sample of U.S. adults ages 18 and older who self-identified as LGBTQ was selected for this study. NORC’s TrueNorth calibration was used to adjust the weights for the nonprobability sample to bring weighted distributions of the nonprobability sample in line with the population distribution for characteristics correlated with the survey variables. CAP provided NORC with a survey questionnaire that NORC submitted for approval by an Institutional Review Board before programming the survey. NORC conducted a pretest and then fielded the survey over three weeks in June 2020. The full results of the study, along with a detailed overview of the methodology, are on file with the authors.
More about AmeriSpeak: AmeriSpeak is a probability-based panel designed to be representative of the U.S. household population. Randomly selected U.S. households are sampled using area probability and address-based sampling, with a known, nonzero probability of selection from the NORC National Sample Frame. These sampled households are then contacted by U.S. mail, telephone, and field interviewers (face to face). The panel provides sample coverage of approximately 97 percent of the U.S. household population. Those excluded from the sample include people with P.O. Box-only addresses, some addresses not listed in the U.S. Postal Service Delivery Sequence File, and some newly constructed dwellings. While most AmeriSpeak households participate in surveys by web, noninternet households can participate in AmeriSpeak surveys by telephone. Households without conventional internet access but with web access via smartphones are allowed to participate in AmeriSpeak surveys by web. AmeriSpeak panelists participate in NORC studies or studies conducted by NORC on behalf of governmental agencies, academic researchers, and media and commercial organizations.
