I’m not sure one can really look at lockdown/mask states vs not. PA was one that locked down and had a mask mandate, but I live here and a lot of people around us and making local news refused to wear masks at all. One of our vocal local politicians is as big of an anti-masker as they make them encouraging anyone who would listen to follow his example.
Stores rarely enforced anything due to the threat of violence or losing business from those who were so anti-mask. H and I would get take out from some restaurants and eat in the car watching various convenience stores. Never was there high mask compliance. At best it got to 50/50 in those stores (going inside, not just gassing up).
There were a whole bunch of restaurants that opened for indoor dining in spite of the official lockdown. FB posts showed many locals openly supporting them and encouraging others to do the same. The state tried to cite them, but last I read they’ve dropped all charges. It ended up meaningless if the restaurant wanted to ignore it and many did - lists were posted.
When we traveled I saw far, far more mask compliance in MD and MD has far better numbers than we do, but even then I have no idea what actual compliance was - just what I saw.
Anyone using stats from that is using dubious standards. Laws can be written, but if they aren’t enforced at all, do they count?
