Reading this plate
58.4% of the population, weighting each district by its own population. The unweighted mean of the 64 district shares is 62.8% and would overstate it. Modelled river flooding only: no storm surge and no urban pluvial flooding. The population base is WorldPop 2020, about 14% below the 2022 census, so read the share rather than an implied headcount.
