Ray described Mexico City as "the largest metropolitan city in the world", which is incorrect, however it is the largest city in North America, which could be what he meant to say. With a metropolitan population of 21,804,515 (2020 census) Mexico City is the fourth largest metropolitan city in the world, and for overall population the fifth largest. The third largest metropolitan city is Shanghai, China with a population of 24,870,895, the second largest is Delhi, India with a metro population of 29,000,000 and the largest city in the world is Tokyo, Japan with a metro population of 37,274,000.
