BACKGROUND A key resource for cross-national comparative research on family dynamics (Andersson and Philipov 2002) is seriously outdated. OBJECTIVE AND METHODS We provide an update of the life-table estimates by Andersson and Philipov (2002) based on data from the Generations and Gender Surveys and other related surveys in 18 countries across Europe and the United States. RESULTS Life-table estimates of family formation of women and men, union dynamics, and children's experience of family disruption and family formation demonstrate the degree of variation in family dynamics across countries. CONCLUSIONS Our findings provide the basis for more in-depth research on the causes and consequences of differences in family dynamics across contexts. CONTRIBUTION The Appendix of the current manuscript is a new resource for comparative research on family dynamics in the early 21st century.
