Are women having fewer children rather than delaying motherhood?
Core argument: Rising childlessness accounts for less than 10% on average of the decline in completed fertility across Latin American cohorts, with the decline driven primarily by reductions in fertility among mothers.
Decompositions by age, education, and age-education groups reveal that the largest contributors to the decline in period fertility were younger women, particularly those of age 20–29, and especially from women with lower levels of education. A cohort perspective based on completed fertility allows us to examine whether these changes arise from women postponing motherhood or ultimately having fewer children. Our analysis shows that successive cohorts of Latin American women are not merely delaying births but rather are having fewer children on average. Furthermore, the decomposition analysis shows that declines in completed fertility are driven primarily by reductions in fertility among mothers rather than by rising childlessness. In this respect, Latin American patterns differ markedly from those observed in the United States: while changes in cohort childlessness play the main role in explaining the modest increase in completed fertility in the US between the mid-1950s and mid-1970s cohorts, rising childlessness accounts for less than 10% on average of the decline in completed [LAC] fertility.
