In many developing countries, fertility has declined steadily in recent decades, while the average strength of family planning programs has increased and social conditions have improved. However, it is unclear whether the synergistic effect of family planning programs and social settings on fertility, first identified in the 1970s, still holds.
Data from 40 developing countries in which Demographic and Health Surveys were conducted in 2003-2010 were used to examine associations among socioeconomic conditions, family planning program effort strength and fertility. Cross-tabulations and multiple regression analyses were conducted.
Variation among countries in scores on the Family Planning Program Effort Index, but not on the Human Development Index, has diminished since the 1970s. On average, fertility levels were lower among countries with better social settings or stronger family planning programs than among those with poorer settings or weaker programs; they were lowest in the presence of both good social settings and strong programs. In addition, fertility was positively associated with infant mortality and negatively associated with female education, but not associated with poverty. About half of the 2.3-birth difference in fertility between countries in Sub-Saharan Africa and those elsewhere can be attributed to differences in program efforts and social settings.
Policies focused on improving levels of female education, reducing infant mortality and improving family planning services can be expected to have mutually reinforcing effects on fertility decline.
在许多发展中国家,生育率在近几十年稳步下降,而计划生育项目的平均力度增强,社会条件改善。然而,目前尚不清楚计划生育项目和社会环境对生育率的协同作用是否仍然存在,这种协同作用在 20 世纪 70 年代首次被发现。
使用 2003-2010 年在 40 个发展中国家进行的人口与健康调查的数据,考察社会经济条件、计划生育项目力度与生育率之间的关系。进行了交叉表和多元回归分析。
自 20 世纪 70 年代以来,计划生育项目力度指数得分的国家间差异有所缩小,但人类发展指数得分的国家间差异没有缩小。与社会环境较差或计划生育项目较弱的国家相比,社会环境较好或计划生育项目较强的国家的生育率较低;而社会环境良好和计划生育项目较强的国家生育率最低。此外,生育率与婴儿死亡率呈正相关,与女性教育水平呈负相关,但与贫困无关。撒哈拉以南非洲国家与其他地区国家之间生育率相差 2.3 个孩子,其中约一半可归因于项目力度和社会环境的差异。
旨在提高女性教育水平、降低婴儿死亡率和改善计划生育服务的政策有望对生育率下降产生相互加强的影响。
