Which World City -- not NYC! -- Has the Highest Population Density?

And the answer is ...

c) Manila

Even if the streets of NYC feel crowded, they pale in comparison to this capital of the Philippines, which boasts an impressive 111,000 people per square mile. Compare that to New York's 27,000 people per square mile and the city starts to feel very spacious. Nearby Union City, in New Jersey, unexpectedly has the highest population density of any incorporated area in the United States, at a paltry 62,000 people per square mile.
