A lot of the discussion revolves around mortality rates, and in particular about NYC as the US epicenter.
Most people I talk to who are thinking about leaving the city aren't concerned about their own risk as a result of being in a dense urban center, rather the lifestyle adjustments are the most difficult thing for them.
Granted that's almost entirely because most people I talk to are relatively healthy young adults who are being responsible and avoiding contact as much as possible, so they're not concerned as much about their own mortality or being a possible vector for others.
