Similar with any UK city other than London and a few small ones, it makes it easy to spot mapmakers who’ve used the metro/borough population based on whether they include Manchester (borough 550k, metro 2.72M), Birmingham (borough 1.15M, metro 2.59M) on their maps… I’ve also seen some include Liverpool though (looking at you hoi4) when it’s smaller than both in all metrics
