  We investigated the dependence of Covid-19 attack rates on demographic and
socioeconomic factors for the communities in Suffolk County (Long Island, New
York State), presently the 5th most-affected county in the United States.
Confirming the previous observations that minorities are disproportionately
impacted by the Covid-19 disease, we found that the attack rate is strongly
correlated with the minority population proportion, with an alarmingly high
$\sim4$-fold attack rate increase for Black and Hispanic populations.
