Population stats

I had heard a rumor about this so verified it on Wikipedia tonight. I think this is rather amazing.

The population density of Portland is 4,200/ sq. mi.

The population density of Hoboken is 30,000/ sq. mi.

By comparison, New York City has a population density of 23,000 / sq. mi. and of the top 20 most populous cities in the US, only San Francisco is second to New York in density, at 15,000.

Hoboken has a population density twice that of Hong Kong (at 6,500 / sq. km, Hoboken is nearly 12,000).
