A fascinating graphic of city sizes, to scale, and their respective populations.
Another graphic compares the respective sizes of Atlanta and Barcelona, which both have the same populations.
Note the comparison between the respective sizes of similarly populated cities like New York and New Delhi or even Tokyo and Dhaka. In this context, it is worth recollecting that both Delhi and Dhaka have stringent height restrictions, as reflected in their low floor area ratios (FARs), which are orders of magnitude lower than those in New York or Tokyo. This naturally translates into low per capita space availability for residents of these cities, which is reflected in their large shares of slum populations.
