On the time axis
Latest observation of each series, up to 22 September 2026.
Listed health comes from 2 separate sources (DGHS facility register; Hugging Face dataset Mahadih534/all-bangladeshi-hospitals). Each names its categories its own way and counts on its own date, so similar rows can carry different figures. Each row is shown as its source prints it; the sources are not reconciled.
