Populations vulnérables is a yearly journal founded in 2013 by the Laboratoire Interdisciplinaire de Recherche “Sociétés Sensibilités Soin” (LIR3S) at the University of Bourgogne. It focuses on the crossroads between science and local, national, and international issues, publishing research on demography, sociology, epidemiology, and geography. In particular, Populations vulnérables looks at how to define, measure, characterize, and understand vulnerable populations. Each issue features a specific theme. The journal is joining OpenEdition with its four latest issues.
