This article examines the effect of socio-economic factors (education, place of residence, region of woman and woman cohort) on age at first marriage among Algerian women and the relative effects between generations of women. The data used are drawn from the MICS-4 multiple indicator cluster survey in Algeria from 2012-2013. Survival models, especially Cox's proportional hazard model in addition to the multiple linear regression model, are used to analyze the data. The results show that education has a positive effect remains robust for almost all generations of women. Significant disparities are found in the place of residence and the woman's region, where urban women are found to be associated with a lower luck of marriage than rural women. In addition, early marriage is more marked among southern women, then women in the High Plateau and in the end, women of the North with some differences in terms of coefficient.
