Using event history data from the 1990 Canadian Family and Friends Survey, this study examines several factors that influence the likelihood of remarriage for women and men whose first marriages ended in widowhood. Our results suggest that large sex differences in remarriage exist, with ever-widowed men having appreciably higher rates than ever-widowed women. Remarriage rates are shown to vary by indicators of lifecycle and by socio-economic status. The implications of these results are discussed.
