Background: In 2017, 785 million people globally lacked access to basic drinking water services and 2 billion lived without sanitation services, mostly in low- lower-middle-income countries. We aimed predict the coverage of by 2030, under two conditions: following current trends accelerating poverty reduction. Methods: Households reporting facilities practicing open defecation were extracted from 210 nationally representative Demographic Health Surveys Multiple Cluster Indicator (1994-2016) including 51 A Bayesian hierarchical, mixed effect linear regression model was developed indicators 2030 at national, rural-urban wealth specific levels. with 95% reduction applied assess contribution these indicators. Findings: Out countries, only nine (Bangladesh, Bhutan, Ghana, India, Nepal, Pakistan, The Philippines, Togo Vietnam) predicted reach over 90% 2030. However, none achieved for services. Twenty-one countries target less than 10% households defecation. disparities especially sanitation, more pronounced Sub-Saharan Africa. By reduction, sector rural settings benefitted considerably. Interpretation: Achieving eradication targets has a substantial positive impact on supply many will struggle achieve goal universal sector.Funding Statement: KTS funded Ministry Education, Culture, Sports, Science Technology, Japan.Declaration Interests: authors declared there no conflict interest.Ethics Approval Not required.
