As if there were not clear, published guidelines for such things. In about 6.8 seconds I found this page for my own U. S. county to get you started: https://kingcounty.gov/depts/health/covid-19/data/key-indicators.aspx https://kingcounty.gov/depts/health/covid-19/data/key-indica...

So I believe it unnecessary to act as if there are not easily-accessed answers to your questions.
