An extension of this work, using ecological inferential techniques to estimate the bases of the Nazi party support, is the subject of my current research. An early version of this extension will appear in Annals, Association of American Geography (see Recent Publications).
This research was supported by the Geography and Regional Science program of the National Science Foundation.
There is also a map showing estimated NSDAP turnout. The value for each of the approximately 1000 Kreisunits was calculated using Gary King's ecological inference method. The map shows the estimated ratio of NSDAP supporters who turned out in the 1930 election in each area. See also Figures 1-4.
