France"

Summary : Union dissolution are determining
factors in life trajectories. It affects the
economic conditions and well-being of separated
people. Since the 1970s,
the number of separations has dramatically
increased in Western countries.
Within youth, the first separation contributes
to the delay of the entry into
adulthood. It also strengthens the growing
diversification of professional,
residential and family-life trajectories. First
separation becomes a frequent
stage in the life of a young adult. In
demographic and sociological research,
the factors and effects of these separations on
early adulthood are largely
under-explored and poorly documented.
This project analyses the place of the first
coresidential partnership
dissolution among all the demographic events of
transitions to adulthood in
France and Belgium, since the end of the 20th
century. Longitudinal
administrative and survey data are used to
reconstruct youth life
trajectories, to identify the separation and
analyze its mechanisms. This
study is based on the coupling of Belgian
Register and censuses, as well as
the French Permanent Demographic Sample, in
addition with the “European
Statistics on Income and Living Conditions”
(EU-SILC) and the French
“Etude des Parcours Individuels et Conjugaux”
(Epic) survey. Event history
analysis and sequence analysis are used to
determine whether the first
separations result mainly from short unions,
without marital or parental
commitment. The results will be distinguished
at the individual level by
gender and social class. The implications of
these separations on
residential mobility, the housing market and
parental financial assistance for
young people will then be explored.
