title: Contraceptive failure in the United States: revised estimates from the 1982 National Survey of Family Growth.
abstract: It is estimated that only about half of all abortions occurring during the period covered by the 1982 National Survey of Family Growth were actually reported in the survey; thus, contraceptive failure rates calculated from these data are almost certainly inaccurate. An attempt to correct for the underreporting of abortion indicates that actual 12-month use-failure rates are more than one-third higher than those calculated without taking abortion underreporting into account, with rates ranging from six percent for the pill to 14-16 percent for the condom, diaphragm and rhythm and to 26 percent for spermicides. Patterns of contraceptive failure are similar to those found in earlier studies.
