This is a really interesting point, thank you. I hadn't realized NYC's population as a whole was only up 300,000 since 1950, either. Maybe most interesting, the 2 boroughs that gained population are larger (combined) than the 3 that lost it, and even today Queens and Staten Island have the lowest population density. The metro area has grown massively, but for the city proper it looks like not only has growth been slow, it's been steadily evening out density. I wonder how this has played out elsewhere; are there patterns of outcome (and relative unhappiness cause) for population spikes/declines and for lower, prolonged levels of excess demand?
