Data review

Nothing is filtered out of The Urban World. Every urban centre in GHS-WUP R2025A appears in the rankings, search, the directory and on the map, with the figures JRC published and their confidence beside them.

This page lists the centres that trip at least one diagnostic rule: low confidence, population jumps, tiny or barely built footprints, missing names. It is the working surface for deciding whether a curation rule is ever needed. How each rule is defined.

5,563 of 21,777 urban centres trip at least one rule.

Population more than doubles or halves between two epochs
