Sociologists at CREST use empirical data and quantitative methods to study questions of stratification and social inequality. We have a strong expertise in statistical methodology and a rich practice with national and international datasets. Our current work addresses questions of social mobility and inequality; demography, gender and the family; consumption and spending; lifestyles and cultural practices; environmental attitudes and actions; social networks; economic sociology; migration and immigration; health inequalities. Our monthly research seminar brings together French and international scholars and we have a proactive visiting scholar policy. Our faculty is also invested in the training of future quantitative sociologists. We teach courses in the ENSAE curriculum and in the Master program in Quantitative Sociology and Demography. We have a dynamic group of doctoral students who participate actively in the daily life and research activities of the department.
