MPIDR Population History GIS Collection
The Mosaic project identifies, gathers, harmonizes, and distributes surviving historical census microdata for Europe and beyond. It aims at building a comprehensive and detailed resource for the historic study of populations by historians, demographers, economists, and other researchers. The Mosaic project builds on historical integrated census microdata projects such as the Integrated Public Use Microdata Series (IPUMS) and the North Atlantic Population Project (NAPP). Records are distributed in the same integrated format, so that historical comparisons can be made across time and space.
