Automated Extraction and Analysis of Individual Data from a Century of French Census Records

Core Concepts

The Socface project aims to automatically extract and analyze individual-level data from over 30 million handwritten census records in France spanning 1836 to 1936, enabling unprecedented insights into social change over a century.

Abstract

The Socface project is a collaborative effort between archivists, demographers, and computer scientists to process and analyze French census documents from 1836 to 1936 on an unprecedented scale. The census records contain handwritten lists of individuals organized by household, providing a unique window into the demographic fabric of France over this 100-year period. The key challenges include: Collecting and normalizing the diverse set of census documents dispersed across 100 local archives, with varying formats and metadata standards. Developing a single deep learning model capable of accurately recognizing and structuring the handwritten personal information, despite the considerable diversity of document layouts and formats over time. Leveraging High-Performance Computing (HPC) resources to efficiently process the massive dataset of over 30 million images. The project has made several key contributions: A reliable method for collecting, organizing, and normalizing the census document images and metadata from the various archives. A comprehensive deep learning model that can directly process full pages of handwritten tables, extracting and categorizing the individual-level information without the need for prior segmentation. An extension of the Arkindex document processing platform to seamlessly integrate with HPC systems, enabling efficient distributed processing of the large-scale dataset. The extracted data will be made freely available to the public, allowing anyone to browse hundreds of millions of historical records. Demographers will use the data to analyze social change over time, significantly improving our understanding of French economic and social structures.

Stats

The census records contain information such as name, age/year of birth, occupation, and household position for each individual. The project aims to process over 30 million images of census documents. The dataset includes census records from 1836 to 1936, with the exception of 1871, 1916, and 1941 due to historical events.

Quotes

"The Socface project aims to take advantage of this archival material to produce a database of all individuals who lived in France between 1836 and 1936, which will be used to analyze social change over the course of 100 years." "An important impact of Socface will be public access to the nominal lists: they will be made freely available, allowing anyone to browse hundreds of millions of records."

Deeper Inquiries

How can the extracted data be used to study the impact of major historical events, such as wars or economic crises, on the demographic and social structures of France over the 100-year period?

The extracted data from the French census lists spanning a century can provide valuable insights into the impact of major historical events on the demographic and social structures of France. By analyzing the data before, during, and after significant events such as wars or economic crises, researchers can track changes in population distribution, household compositions, occupations, and other socio-economic indicators. For example, during times of war, shifts in population demographics such as changes in the gender ratio, age distribution, and occupational patterns can be observed. The data can reveal migration patterns, displacement of individuals, and changes in family structures due to the impact of war. Economic crises may also be reflected in the census data through fluctuations in employment rates, income levels, and living arrangements. By comparing census data from different time periods, researchers can identify trends and patterns that coincide with specific historical events. This analysis can help in understanding how wars or economic downturns influenced population dynamics, social mobility, and community resilience over the 100-year period covered by the census records.
