 * Hi Cchris - In response to your question posted on the NYC talk page regarding pop density: your calculation is correct in theory but leads to an incorrect result. Pop density is derived by dividing pop by area, as you suggest. The difficult is in identifying a correct denominator. The figure you used of 468.9 is incorrect: that is the total area of the city, including bodies of water such as New York harbor. After correcting for bodies of water, the city's land area is actually 321 sq miles. This number gets us closer to calculating density correctly. However, the 321 sq miles includes the city's 28,000 acres of parkland and many thousands of acres belonging to JFK and La Guardia airports, where people cannot live. I don't know whether the Census Bureau makes exemptions and uses only "livable" land area, or whether it simply uses total land mass. The point is that this seemingly simple calculation is not so straightforward upon closer examination. Momos 23:24, 11 April 2007 (UTC)
