I was interested in how Pew went about gathering the data to arrive at this result. In particular, I wanted to know if this reflects only legal/registered ownership and what the level of confidence is in the results.
From the Pew website:
“Everyone who took part is a member of Pew Research Center’s American Trends Panel (ATP), an online survey panel that is recruited through national, random sampling of residential addresses…survey was conducted with 10,606 ATP members from June 14-27, 2021”
So….the result you focused on represents ~10k people with addresses. I could find no +/- level of confidence. Other than heritage, no other demographics were cited. There was no indication whether non-legally obtained firearms possession was included.
I suspect you can guess that I have a great deal of skepticism regarding this study.
