Indonesian family planning (FP) service statistics indicate that three out of five couples of childbearing age nationwide are now using modern contraception provided by the FP program. The 1980 Indonesian Census provided a unique opportunity to cross-check the FP program's contraceptive prevalence figures for every province. The results of that comparison indicate considerable variation, particularly in Java, between the FP program estimates of numbers of current users and the census estimates. Possible explanations for these differences are sought in the FP program approach to estimation of prevalence levels from acceptor data, and by examining the possibility of census underestimation of prevalence levels.
印度尼西亚计划生育（FP）服务统计数据表明，全国五分之三的育龄夫妇目前正在使用由计划生育项目提供的现代避孕方法。1980年印度尼西亚人口普查提供了一个独特的机会，用以交叉核对计划生育项目针对每个省份的避孕普及率数据。该对比结果显示出相当大的差异，尤其是在爪哇岛，计划生育项目对当前使用者数量的估计与人口普查估计之间存在差异。这些差异的可能解释可从计划生育项目根据接受者数据估计普及率水平的方法中寻找，并通过研究人口普查低估普及率水平的可能性来探寻。
