a00.csv - Births of 2000 in France
From Didier Castille data

This dataset contains all births in France of year 2000.

Anonymous data
Birth day but no birth time

In 2020, at the initiative of Nick Kollerstrom, I (Thierry Graff) could contact Didier Castille and he sent us a sample of his data.
He agreed to make them publicly available online but asked to accompany the data with this notice:

These files are not INSEE files, they are INSEE files adapted by D. Castille.
These files are neither official nor scientifically valid because they depend on the good faith of D. Castille.
