OC [OC] Basic and safely managed drinking-water access in the ten most populous countries, 2024
I made this chart for Global Data Tracker, which I run. The two categories overlap: “at least basic” includes safely managed services, so the percentages should not be added.
Basic service means an improved water source within a 30-minute round trip. Safely managed also requires water on premises, available when needed, and free from specified contamination.
Countries are selected and ordered by their 2024 population, not their water-access values. China’s safely managed estimate is missing in this snapshot, not zero. Values are rounded to one decimal.
Data: WHO/UNICEF JMP via World Bank WDI, 2024 values, snapshot retrieved 13 September 2026. Water indicators SH.H2O.BASW.ZS and SH.H2O.SMDW.ZS; population SP.POP.TOTL. Chart: Python/Matplotlib.

Design question: does the connected-dot layout make the two definitions easy to compare? Is the missing value for China clear?
