In France between 1795 and 1815, the governments of the Directoire, the Consulat, and the Empire undertook an immense amount of regional description and recording.
This significant body of primary source documents, edited by Jean-Claude Perrot, is available as a microfiche collection consisting of four sections: methodological works (government questionnaires to prefects, essays on statistics), fundamental periodicals of a statistical nature, general works on a national scale, and the mémoires or replies by prefects to questionnaires from the national government. Statistical Sources under the Empire (Enquêtes des préfets) is a valuable resource for historians, students of statistics, sociologists, economists, and demographers.
