Childhood vaccination rates are sliding in communities across the United States, according to an NBC News data investigation.
How much vaccination percentages have fallen and where exactly have been kept in state health department files — or not tabulated at all. Now this data, covering more than 3,000 counties and other jurisdictions, is in one place.
Doctors say that vaccination rates of 95% or higher are necessary to protect against disease outbreaks. In the 2019-2020 school year, 6 in 10 of the counties and jurisdictions tracking measles-mumps-rubella vaccinations met that threshold. But in the latest data, fewer than 4 in 10 do.
Use this map to see the childhood vaccination rates for the place where you live, and then see how that figure has changed over time. Underneath the map and the chart is data on vaccine exemption percentages — what share of school-age children have legal permission, whether for medical or nonmedical reasons, to not be vaccinated.
