Looking at the census does give you a better indication of who is living where and also what the population is like, and it does tend to throw up a few surprises.
The 2010 census in New York City certainly had its fair share of surprising statistics that even went against what the authorities themselves would have you believe. Take Central Park because the authorities state that nobody lives there, and why would they admit that when it is such a huge draw for tourists and natives alike?
However, it seems that the census has a different idea of what is going on because according to the census there are a total of 25 people that refer to Central Park as being their home. It does just make you think about what their accommodation is going to be and also how it will be scary for them at night, but then they could also argue that they have one of the most prestigious addresses in the entire city.
