How CityEvidence calculated the snapshot
Absolute change is the later source value minus the earlier source value. Percentage change is that difference divided by the earlier value. Annualized change uses compound annual growth across the stated interval. Projection comparisons use the UN projection already present in the source series; CityEvidence does not extend or alter the population model.
