How to read this state summary

A distribution of county estimates, not resident prevalence

Counties are equally weighted in every summary below. Missing or suppressed counties are excluded per measure, so coverage can differ from one measure to another. These values describe the distribution of published county estimates; the source data does not include the measure denominators needed to estimate a resident-level statewide prevalence.
