Question

Which city is bigger in terms of size, not population. New York City or Beijing?

Answer 1

beijing

AM

Answer 2

yup. definitely Beijing

Answer 3

Almost certainly Beijing because NYC is small, because a lot of the metro population is in CT, NJ and other NY towns.

NYC 800 km2 http://hypertextbook.com/facts/2002/Jord...

Beijing

but this chart, which is supposed to be Urban areas, says NY is 5 times larger, perhaps because of mixed definitions of metropolitan and urban
