What Drives Drinking Water And Sanitation Choices Among Vulnerable Households? Evidence From Nigeria

This dataset was sourced from the fourth wave of the Nigerian Living Standard Measurement Survey (LSMS) datasets to determine the socio-demographic and locational factors influencing the households’ choices of drinking water sources (DWS) and sanitation facilities in Nigeria. The explained variables used in this study are access to drinking water sources and access to sanitation sources. Access to improved drinking water sources was operationalised in the questionnaire by asking, “What is the main source of drinking water for the household?”. The household head or the representative was asked to select from sixteen different predetermined drinking water sources with an option of mentioning other sources that were not listed in the options. In the case of access to sanitation services, the household head or the representative was asked, “What kind of toilet facility do members of your household usually use?”. The responses were also recoded into open defecation, unimproved and improved based on the JMP ladder for sanitation. The explanatory variables used in this study are the total number of rooms in a dwelling, water time, electricity, dependency ratio, household head education, average household years of education, household size, gender, age, marital status, region, wealth index and zone. These variables were operationalised differently. Variables such as number of rooms, water time, dependency ratio, household head education, average household years of education, household size, age and wealth index are continuous. In contrast, electricity gender, age, marital status, region, and zone are categorical. The household wealth index was calculated using characteristics relating to household asset ownership, such as radio, washing machine, guitar, and refrigerator ownership.本数据集源自尼日利亚生活标准衡量调查（Nigerian Living Standard Measurement Survey, LSMS）第四轮数据，旨在探究影响尼日利亚家庭饮用水源（Drinking Water Sources, DWS）与卫生设施选择的社会人口学及区位因素。 本研究选取的被解释变量为饮用水源可达性与卫生设施可达性。其中，改善型饮用水源可达性的调研问题设置为：“您家庭的主要饮用水源是什么？”，受访户主或家庭代表需从16种预先设定的饮用水源选项中进行选择，也可补充说明列表未涵盖的其他水源。 针对卫生服务可达性，调研问题为：“您家庭成员日常使用的厕所设施类型是什么？”，调研结果依据卫生联合监测项目（Joint Monitoring Programme, JMP）的卫生设施分级标准，被重新编码为露天排便、非改善型与改善型三类。 本研究使用的解释变量包括住宅总房间数、取水时间、电力供应情况、抚养比、户主受教育程度、家庭平均受教育年限、家庭规模、性别、年龄、婚姻状况、所在区域、财富指数以及地域分区。上述变量采用了不同的操作化方式：其中房间数、取水时间、抚养比、户主受教育程度、家庭平均受教育年限、家庭规模、年龄及财富指数为连续型变量；而电力供应、性别、年龄、婚姻状况、所在区域及地域分区则为分类变量。 家庭财富指数基于家庭资产所有权特征进行计算，所涉及的资产包括收音机、洗衣机、吉他以及冰箱等。
