ABSTRACT
This article outlines how current sociology constructs life courses. First, a set of general heuristics is provided. Second, the development of life course sociology over the last 50 years is traced as an intellectual process whereby the life course has emerged as an analytical construct in addition to such concepts as human development, biography, and aging. A differential life course sociology has gradually developed in which contexts are specified according to time and place. Third, these differential constraints operating on life courses are illustrated from the perspective of 2 research areas. One perspective introduces historical periods as a sequence of regimes that regulate life courses. Another perspective looks at cross-national differences and especially focuses on institutions as the mechanisms by which life courses are shaped. The article concludes with reflections about the relation between the variable social contexts of life courses and human development.
