Fig. 2: Country-level predictors of concern about drinking water.
From: Self-reported anticipated harm from drinking water across 141 countries
Percentage of the population in each country that anticipated harm from their drinking water in the next two years in 2019 by A water availability (log renewable freshwater resources, m3/capita) in 2017 (N = 136 countries)72, B water infrastructure (percentage of population with at-least a basic drinking water service level) in 2019 (N = 135 countries)4, C percentage of wastewater that was treated in 2015 (N = 137 countries)73, D self-reported experienced drinking water harm in 2019 (N = 141 countries), E water-related mortality (percentage of deaths in the country attributable to water; shaded region represents countries with ≥1% of deaths attributable to unsafe water) in 2019 (N = 138 countries)74, F economic development (log gross domestic product per capita, USD) in 2019 (N = 137 countries)75, and G quality of public governance (Corruption Perceptions Index score) in 2019 (N = 140 countries)41. Model coefficients and 95% confidence intervals are in Table 1. Data are presented as observed values (circles) and predicted values (black line) with associated 95% confidence intervals (gray area) based on fitted weighted least squares regressions with robust standard errors. Tests were two-tailed.
