This paper was designed to alert economic development practitioners about pitfalls in comparing communities’ Covid-19 cases using absolute and/or relative measures of change; the net shift method is recommended for such comparisons. Net shift computations involve measuring the relative size of increases or decreases in Covid-19 cases in counties vis-à-vis the regional norm.
