Family planning efforts by the Pakistan government were greatly expanded during its third Five-Year Plan (1965-70). Cross-sectional data obtained from the 1968-1969 IMPACT Survey are analyzed to determine the relative importance of demand and availability factors in explaining the response of Pakistani couples to the program's efforts. The findings indicate that the proportion of couples who express interest in controlling their fertility in the future is larger than the proportion who report current use of a family planning method. The analysis, however, shows that the program delivery system did not reach most of those who indicated they were potential users. When adequate availability was reported, family planning was adopted despite existing traditional social constraints; nonetheless, the analysis also points out that the potential of the program was severely limited by these constraints.
巴基斯坦政府的计划生育工作在其第三个五年计划（1965 - 1970年）期间得到了极大扩展。对1968 - 1969年影响调查获取的横断面数据进行分析，以确定需求和可及性因素在解释巴基斯坦夫妇对该计划努力的反应方面的相对重要性。研究结果表明，表达未来有控制生育意愿的夫妇比例大于报告目前使用计划生育方法的夫妇比例。然而，分析显示该计划的实施系统并未覆盖大多数表明自己是潜在使用者的人群。当报告有足够的可及性时，尽管存在传统社会限制，计划生育仍被采用；尽管如此，分析也指出这些限制严重制约了该计划的潜力。
