Underlying Family-Size Preferences and Reproductive Behavior

Although about half the married women in a US survey said they wanted one or two children, underlying family-size preferences indicate a potential for many to have larger families. Using a measure of family-size preference that probes beyond single-valued statements, it is found that identical stated family-size desires or intentions may have different meanings for different people. Differences are systematically related to the stage in family building at which contraception begins, to current (or likelihood of future) use of effective methods, to the probability of continued childbearing, and to unwanted pregnancies.
