Between 1970-1980, approximately 942,000 women 15-24 years of age underwent tubal sterilization in the United States. These women represented about 17 per cent of all women ages 15-44 years who underwent tubal sterilization in the United States during this 11-year period. During 1970-1980, sterilization rates rose steadily from three per 1,000 to 11 per 1,000 for women in the 20- to 24-year age group, but remained stable at less than one per 1,000 for women in the 15- to 19-year age group. For each year, rates for Black women were greater than those for White women. Sterilization rates increased over the time period for both currently and previously married women, but remained low for never-married women. Most tubal sterilizations were performed after delivery of an infant.
1970年至1980年间，美国约有94.2万名15至24岁的女性接受了输卵管绝育手术。在这11年期间，这些女性约占美国所有接受输卵管绝育手术的15至44岁女性的17%。1970年至1980年期间，20至24岁年龄组女性的绝育率从每1000人中有3人稳步上升至每1000人中有11人，而15至19岁年龄组女性的绝育率则稳定在每1000人不到1人。每年，黑人女性的绝育率都高于白人女性。在此期间，已婚和曾婚女性的绝育率均有所上升，但未婚女性的绝育率仍然较低。大多数输卵管绝育手术是在分娩后进行的。
