We have two possible hypotheses.

There is an unknown quality about New York that causes the virus to be 4 times more severe.

A self-selected group from the internet demonstrated self-selection sampling bias.

I know where I would put my money.

I think there's significant error bars all around. Note that the New York data is older than the SCC data, so there's delay related effects, too.

We can quibble a whole lot with exact effect magnitudes and data analysis techniques, but...

In any case, we have a whole lot of data (Iceland RTPCR, Gangelt RTPCR, Switzerland RTPCR, Netherlands blood donation serology, Santa Clara County serology) that indicates infection rates likely exceed case rates by 10x or more in areas with relatively good testing availability.
