Of the 464 women, 192 knew of no contraceptive methods and therefore had used none. The remaining 272 women knew of one or more methods, more or less effectual, for the prevention of conception. Of the 192 women who were ignorant of the use of contraceptives, practically one half, or 104, had a history of abortions, with a total of 202 abortions, or an average of two apiece. In contrast with this, of the 272 women who knew of one or more contraceptives, only one fourth, or seventy-two, had undergone abortions, with a total of 122 abortions, or an average of only 1.6 apiece. A further analysis of our tables shows an interesting and striking relationship between ignorance of methods for the prevention of conception and the number of children. Sixty-eight women had had three children each. Of these, twenty-six, or thirty-eight per cent., were ignorant of contraceptives. Twenty-eight women had had four children each. Of these fourteen, or fifty per cent., were ignorant of contraceptives. Fifty-five women had had five children each. Of these thirty were ignorant of contraceptives, or fifty-four per cent. Thirty-two women had had six children each. Of these twenty were ignorant of contraceptives, or sixty-two per cent. Forty women had had seven children each. Of these thirty-eight were ignorant of contraceptives, or ninety-five per cent. Twenty-one women had had eight children each. Of these twenty were ignorant of contraceptives, or ninety-five per cent. Forty-four women had had nine or more children each, and of these all were ignorant of contraceptive measures. Arranged in tabular form, these data would appear as follows: Number of Women Number of Number Ignorant Percentage Children of Contraceptives 68 3 26 38 28 4 14 50 55 5 30 54 32 6 20 62 40 7 38 95 21 8 20 95 44 9 to 17 all 100 It is sometimes stated by opponents of birth control that contraceptive methods are known by every married person and that the fault and immorality of having a large family of unprovided for dependents lies not in ignorance of contraceptives but rather in a lack of determination on the part of one or both parents to use preventive measures; in other words, that the failure to use contraceptives results from the inconvenience attending some methods and also from the influence of religious sentiment.
