The population of Manhattan ALONE is 1,620,867. I just passed an updated sign for my hometown; it read 3,406 (that's a population spike of nearly 400 since the old sign made its debut, folks).
The most expensive Upper East Side penthouse (in The Pierre Hotel) was listed in the classifieds for approximately $70 million, and the most expensive townhouse was listed for $75 million. In the newspaper earlier today, I saw that in my hometown you can rent a brand new one bedroom apartment for $300 a month.
That is all.
