What we’re less sure of3 of 7 claims
Medium
Luanda is projected to overtake São Paulo in population within about 20 years and Shanghai within about 60 years.
The projection is tied to the cited dataset, but the approximate crossover dates are model-dependent.
Medium
São Paulo is near its population peak, while Shanghai is projected to peak around 2050.
Supported by the cited projection series, but peak timing depends on model assumptions.
Medium
The urban-growth shift will direct much of this century’s demand for housing, transportation, water, and power toward rapidly expanding African cities.
Plausible inference from the projected growth pattern, but not directly quantified in the story.
