The sociology of lifestyles seeks to describe and explain the configuration of individual and social group practices and values. It is based on a model of social stratification structured by economic resources and educational attainment, viewed as expressions of social distinction. Since the post-war period, the democratisation of consumer goods and the expansion of the cultural sphere have fostered the emergence of a 'differentialist' perspective on lifestyles. These two models are tested through a statistical analysis of data from Kantar's 2020 TGI survey, conducted among 15,049 French respondents aged 15 and over. This survey covers a wide range of domains: hobbies, holidays, cultural and media practices, sports, clothing, diet, household equipment, housing, cars and retail. A factor analysis reveals two main structuring principles: on the one hand, a differentiation principle shaped by age, gender and life course, on the other hand, a principle of distinction linked to economic and cognitive resources. In the discussion section, this article suggests interpreting the first model through the concepts of social-biographical 'concernedness' and attachment, and the second through financial and cognitive capacities.
