Sterilisation has been increasing in the United States in recent decad
es. Using the National Survey of Families and Households, this paper e
xamines sterilisation among married couples using event history techni
ques, viewing husband and wife sterilisation as competing risks. Wives
are more likely to experience sterilisation and at shorter durations
of marriage. Number of children has a curvilinear effect on sterilisat
ion, increasing and then decreasing its likelihood. Wives who are olde
r than their husbands are more likely to get sterilised themselves. Bl
ack and Hispanic husbands are more likely to undergo sterilisation.
