Household levels of deprivation to water, sanitation, and hygiene (WaSH) and residential conditions in slum settlements of Lagos, Nigeria were assessed and mapped using slum deprivation index (SDI). A structured questionnaire was administered to 1,398 households in 16 settlements using a random sampling method. Descriptive statistics and SDI were employed to analyze the data while ArcMap was used to map the patterns of SDI. The results show that households live in poor dwelling conditions with limited access to WaSH facilities. The SDI indicates that 18.7% of the slums are highly deprived. Based on WaSH and dwelling and physical environment (DPE) components, 18.75 and 31.25% of the slums are highly deprived. Water, sanitation, and hygiene indicators show that 37.5, 12.5, and 56.25% of the slums are highly deprived respectively. About 50, 37.5, 43.75, and 31.25% of the slum are highly deprived based on dwelling, waste disposal, waste pile, and stagnant water respectively. The study concluded that six settlements live in deplorable WaSH and DPE conditions. The study recommends urgent intervention for planning and resources allocation, and sustained urban renewal programs at Oko-Baba, Ilaje, Oko-Agbon, Abule-Nla, and Badia for improved WaSH and living conditions for sustainable service delivery and healthy slum settlements.

使用贫民窟剥夺指数（SDI）评估和绘制了尼日利亚拉各斯贫民窟居民家庭的水，卫生和卫生（WaSH）匮乏水平以及居住条件。使用随机抽样方法，对16个居民区的1,398户家庭进行了结构化问卷调查。描述性统计数据和SDI用于分析数据，而ArcMap用于映射SDI模式。结果表明，家庭生活条件差，无法使用WaSH设施。SDI表明，贫民窟中有18.7％的土地被高度剥夺。基于WaSH，居住环境和物理环境（DPE）组件，贫民窟的18.75％和31.25％被高度剥夺。水，卫生和卫生指标显示，分别有37.5、12.5和56.25％的贫民窟被高度贫乏。大约50、37.5、43。根据居住，废物处置，废物堆积和积水，贫民窟被高度剥夺的比例分别为75％和31.25％。研究得出结论，六个定居点生活在恶劣的WaSH和DPE条件下。该研究建议对Oko-Baba，Ilaje，Oko-Agbon，Abule-Nla和Badia的规划和资源分配采取紧急干预措施，并进行持续的城市更新计划，以改善WaSH和生活条件，以实现可持续的服务提供和健康的贫民窟定居点。
