Prussian Historic Data

The ifo Prussian Economic History Database (iPEHD) is a county-level database for all Prussian counties, 1816-1901. These data are an excellent source for empirical research and, above all:

"The data are provided free of charge. We have tried to document the data as good as - we think - we possibly could, including references to the original publications from which the data are drawn."

In addition, the data are well documented: Becker, Sascha O., Francesco Cinnirella, Erik Hornung and Ludger Woessmann, "iPEHD - The ifo Prussian Economic History Database", CESifo Working Paper No. 3904.
