A few days ago, I mentioned that Mongkok is Hong Kong’s most densely packed neighborhood. Just how dense is it? Try roughly 165,000 people per square kilometer, or well over 400,000 people per square mile.
By comparison, Manhattan (i.e. New York County) has a population density of a mere 67,000 people per square mile (the highest in North America).
yeah, but that's probably counting all those damn parks we have. take that out and i'm sure we'd have a more impressive showing.
We also aren't nearly as vertical living as those folks.
Melbourne, the 2nd largest city in Australia (approximately 3.5 million inhabitants), has a population density of roughly 4,200 people per square mile.
You're still comparing apples to oranges. Compare neighborhood with neighborhood.
In this case, the most densely populated neighborhood of the USA is the Upper East Side, which is (according to this, although I thought it was the Upper West Side) 109,600 people per square mile.
