This paper presents a comprehensive contextual database designed to enhance the understanding of demographic phenomena by integrating socioeconomic measures at multiple geographic levels in France. The database was developed to support the "Trajectories and Origins 2" (TeO2) survey and contains approximately 400 indicators derived from the 2018 French population census, harmonized historical census data, and other administrative sources. These indicators provide valuable context on immigration, socio-economic structures, and living conditions, allowing for a fine-grained analysis of demographic behaviors. By linking geographic context to survey data, this database offers a robust tool for examining the impact of the local environment on individual life trajectories. The database covers various geographic levels including IRIS, municipalities, and employment zones, and is planned to be made available to researchers through a secure data hub. Future work will focus on developing a visualization tool for easy data access and updating the database with new data releases.
