Henri Leridon was born on 15 July 1942 in Algiers, where his father was an officer. He is a French demographer and director of research emeritus at the Institut national d'études démographiques.

Biography

After studying at the Lycée Hoche, he entered the École Polytechnique. He joined Ined as a project manager in 1965, obtained a diploma as a demographer from the Institute of Demography of the University of Paris and a diploma of higher education in economics. In 1972, he obtained a doctorate in economics.
He spent most of his career at Ined. In 1974–75, he was a visiting professor at the University of Pennsylvania and, from 2001 to 2006, he headed a unit of Epidemiology, Demography and Social Sciences at Inserm, a mixed unit with Ined and Paris XII University.
In 2008–2009, he was an associate professor at the Collège de France, chair of sustainable development.
In 1994, he was elected Correspondent of the French Academy of sciences and, in 2014, Foreign Member of the British Academy.

Scientific work

Léridon's work focused first on contraceptive practices and family structures. On these two themes, the Ined surveys he conducted have long been the only reliable statistical sources on evolving practices. He has also devoted himself to the analysis of the fertility of human populations: his research is in line with that of the French demographer and historian Louis Henry, and has focused on the various components of fertility: fertility, intrauterine mortality, postpartum sterility and definitive sterility. He also worked on the recombination of these components in microsimulation models. This model has also made it possible to determine the real effectiveness of assisted human reproduction practices, both individually and collectively.
In 2002, he launched the idea of a large national cohort of children, aimed at monitoring a representative national sample of children from birth to adulthood, to study all aspects of their development in a multidisciplinary approach combining social sciences, health and environmental determinants. The Elfe cohort was formed in 2011, with 18,500 children born throughout metropolitan France, and is still followed by a team based at Ined and involving some 40 research teams.
