With recent advances in information technology--GIS mapping technology, digitized historical archives, digitized parliamentary transcripts, and online historical census reports etc.--it is now possible for scholars to undertake historical quantitative research on elections going back to the 19th century.

Daniel Ziblatt’s "Comparative History of Elections  Program"(CHEP) aims to explore this new area of research by linking and synthesizing two centuries of national census data from as many countries as possible with election, roll call and petition data going back to 1800.

Working in part with the collaboration of other centers at Harvard (including chiefly IQSS, but also CGA, the Center for European Studies, and CAPS), the program will depend on the united effort of faculty, trained graduate students, and undergraduate "junior apprentices" to assemble this body of data and make it publicly available online.  The work of the CHEP will be made further accessible to the academic community through numerous interdisciplinary workshops and conferences.

Scholars involved in the CHEP find themselves at the edge of a new research frontier where technological innovations offer immense and unprecedented opportunities for new scholarly progress.
