DHS dataset

The quantitative work draws on the DHS conducted in African countries. The DHS is an ongoing paper in over 85 low and middle-income countries to construct nationally representative household samples (Corsi et al., 2012). The surveys are conducted at the frequency of three to six years. For Africa, DHSs have been conducted in collaboration with national statistical agencies. The DHS provides detailed information on demographic and social variables at the level of the household, as well as data separately for men, women and children. The demographic information provided includes age, marital status, household size and ethnicity. It also provides socio-economic status markers of individuals and households. These consist of level of education, employment status, household endowment and a wealth index. Table 1 provides the definitions and descriptive statistics on all variables considered in our empirical analyses.本定量研究基于非洲国家开展的人口与健康调查（Demographic and Health Surveys, DHS）展开。人口与健康调查是一项在全球85余个中低收入国家持续开展、旨在构建具有全国代表性家庭样本的调查项目（Corsi等，2012）。该调查每3至6年开展一轮。在非洲地区，人口与健康调查由各国国家统计机构合作实施。该调查可提供家庭层面的人口学与社会学变量详细信息，同时还可分别提供男性、女性及儿童的细分数据。其所涵盖的人口学信息包括年龄、婚姻状况、家庭规模及族群归属。此外，该调查还提供个人与家庭的社会经济地位衡量指标，具体包括受教育水平、就业状态、家庭资产禀赋及财富指数。表1列出了本实证分析中涉及的全部变量的定义与描述性统计结果。
