Performance of county-level estimators for SARS-CoV-2 infections with population taken into account. The hypergeometric infections estimator per capita had low bias and high precision (column 1), displaying superior performance to a naive estimator that used the uncorrected number of COVID-19 cases (column 2). On the x-axis, counties and states are ordered by increasing number of SARS-CoV-2 infections, shown in red.
