Permanent Demographic Sample
The Permanent Demographic Sample (EDP) is the first large-scale socio-demographic panel established in France to study the birth rate, mortality, relationships, geographical migrations within the national perimeter, social and professional mobility and the potential interactions between these different phenomena.
There are two possible approaches to studying these dynamics: surveying people on their past experiences or, using a panel, actually tracking people and accumulating information over time.
The latter approach, that of the Permanent Demographic Sample, takes longer but yields information which is more precise and more reliable, free from the potential bias of memory.
Thanks to its size, the Permanent Demographic Sample allows detailed analyses which can take account of differences between generations and differentiate the various levels of education, background etc.
The Permanent Demographic Sample was established in 1967. It comprises information taken from the official publications of the registry office for births, marriages and deaths since 1968, along with census information from 1968, 1975, 1982, 1990 and 1999.
Information derived from the annual census surveys is also integrated.
Due to restricted resources, registry information was not systematically integrated for all members of the sample group between 1982 and 1997.
