We calculate mortality by linking 139,000 adults recorded as sheltered and unsheltered homeless in the 2010 Census to all-cause mortality data from the Social Security Administration (SSA) up to 2022.

Using the number of 8,248 deaths worldwide (as of March 18 at 11:30 a.m. EDT) and reported cases of 205,470, you would calculate a mortality rate of about 4%. But you would be wrong.
