This paper provides a documentation of the ifo Prussian Economic History
Database (iPEHD), a county-level database covering a rich collection of variables
for 19th -century Prussia. The Royal Prussian Statistical Office collected these data
in several censuses over the years 1816-1901, with much county-level
information surviving in archives. These data provide a unique source for microregional
empirical research in economic history, enabling analyses of the
importance of such factors as education, religion, fertility, and many others for
Prussian economic development in the 19th century. The service of iPEHD is to
provide the data in a digitized and structured way
