Without a lot more background data, or perhaps I need a better understanding of how the chart is designed: It's showing me that there seems to be little rhyme or reason regarding how restricted a lockdown is or not and the reported cases.
We're freewheeling it where I live, and the hospitalized percentages are way, way lower than most of California, with nazi restrictions. Other places that are freewheeling it do have high percentages, but yet others are lower than where I live. Could be reporting differences, could be cultural differences in how peole respond and interact, could be a lot of things. There just, to me, doesn't seem to be much correlation between lockdown strictness and fewer cases percentage-wise.
ETA: Looking at the breakdown data when I click on my county, the largest hospital system in the county is not even listed.
