Reply #6: You both are forgetting that these will most likely be hi-rise apartments. [View All]

If you look at the probability that these apartments will each be at least 20 floors or so the numbers start to look better. According to Wikipedia the population of Manhattan is currently over 35,000 for a comparable amount of space. While this is a smaller number of people you have to take into account the vast amount of space taken up by businesses, so while tight I definitely see this as a workable project.

Once again, I'd like to point out that I'm no Urban Planner, I'm just going by the information I've found online.
