The study investigates the relationship between family structure and lifestyle changes in contemporary Romania, on the social-political background of transition. The objectives of the paper include the theoretical, methodological and empirical characterization of Romanian family lifestyle, and the classification of Romanian families, by their particular ways of living. The superficial relationships create a new need of stability. The individuals select their relationships by the profit possibility and giving an effect of anchorage. So, we may speak not only about career anchorages, but also about lifestyle anchorages. Traditionally, one of these anchorages is the family. But in the last century, the family suffered transformations affecting its stability and diversity. The post-traditional social structures, which promote the success by yourself, favors the appearance of new types of families. The influence of mutations in the system of social values on lifestyles and family environments is traced, in this paper, through a variety of quantitative methods, including factor analysis and multivariate regression. The conclusions of the study are starting points for psycho-sociological analyzes dedicated to lifestyle and for consumer behavior studies.
