Source

Measles counts were obtained from the public SurvStat database of the Robert Koch institute: https://survstat.rki.de/.

A shapefile of Germany's districts as of 01/01/2009 was obtained from the Service Center (www.geodatenzentrum.de) of the German Federal Agency for Cartography and Geodesy (www.bkg.bund.de). The map of the 17 districts of the “Weser-Ems” region (measlesWeserEms@map) is a simplified subset of this shapefile using a 30% reduction via the Douglas-Peucker reduction method as implemented at MapShaper.org.

Population numbers were obtained from the Federal Statistical Office of Lower Saxony (LSN): http://www.statistik.niedersachsen.de/themenbereiche/bevoelkerung/

Vaccination coverage was obtained from the public health department of Lower Saxony: Niedersächsisches Landesgesundheitsamt (2005): Impfreport – Durchimpfung von Kindern im Einschulungsalter in Niedersachsen im Erhebungsjahrgang 2004. Online available from http://www.nlga.niedersachsen.de/gesundheitsberichterstattung/gesundheitsberichte/impfreport/basisberichte-19385.html, also as an interactive version.
