This applies to all cities, but how can anyone "guess" or "feel" what the population is for a massive city like New York? It's like guessing how many items are in a supermarket. Would you notice if they reduced a section you never shop in? We take note of new buildings going up and neighborhoods that get hot, but does anyone notice when people leave?

My Chicago neighborhood lost 11% of it's population last decade, but doesn't feel any different, except maybe a little whiter, but I might be noticing that because I've seen the numbers.
