62% of Trump voters think the 2020s is the worst decade for crime.
Large age gap too. 58% of people aged 65 and older think it is the worst decade for crime. You can't tell me this isn't a media consumption shaped phenomenon.
I don't expect them to know any of this with precision, but it was basically commonplace before the pandemic for people to realize the 80s and 90s were particularly high crime periods. I think people have obviously been influenced by media coverage during the pandemic of crime and think it has gotten worse than even those decades.
I would have been very curious to see this survey done in say 2010.
Though from other crime surveys we do know there is a clear discontinuity in recent years. With a sharp gap among Republicans especially. They think NYC is a hellscape.
To some degree this is probably a regional thing. Crime rates don't move equally everywhere. Also, while I don't think crime is as high now as it was in the 1980s, I do think it is up from the 2000-2019 time range.
