| I also like the idea, but would appreciate more time. As for the source, it seems legitimate, but of course these things are hard to measure, especially in the developing world. Most sources in India these days agree that Delhi is larger than Mumbai. But the National Capital Region consists of several cities, has a fluid population, and legal boundaries aren't even that clear to its residents. So, the City Mayors list seems as good as any. And we have to accept the arbitrariness of city v metro, and the many ways cities decide who is a resident. |
