Methodology
The vaccination data was provided by the state health departments. Addresses for about 16,000 schools in eight states were included in the original data. Locations of the remaining schools were determined by checking against the National Center for Education Statistics’ school directories or the states’ school directory using school name, city, county and/or school district. If there was no unique match, the school’s location was determined with Google Maps API using school name, state and county, city and/or school district. Duplicate locations were analyzed individually.
