The Sierra Club recently put up a density calculator (currently "under construction") at www.sierraclub.org/sprawl/community/enviroimpacts.asp that has been revised a couple of times because it was so absurd. It has gone through the following classifications: "Efficient Urban" 500 housing units per acre (original) "Dense Urban" 400 per acre "Efficient Urban" 100 per acre (revised) "Suburban Efficient" 10 per acre (new) "Sprawl" 1 per acre It drew much derision because, at 2.43 persons per household, 500 per acre (777,000 per square mile) is more than three times as dense as the most dense part of Manhattan and more than twice as dense as the most dense part of Bombay. 400 is still more than twice as dense as Bombay. 100 is double the density of Paris and more than double the density of Manhattan. 10 is about the density of the city of San Francisco and four times as dense as Portland, Orgegon. 1 is, of course, about 40% less dense than the average American suburb. So, Portland is only 1/4 as dense as what the Sierra Club thinks of as "Suburban Efficient". That's what comes of letting innumerate people with a rabid agenda expose themselves in public. See www.demographia.com/db-citydenshist.htm for selected current and historical city densities. The 777,000 per square mile would be be the Lower East Side of New York around 1900, when there was one block in the 11th ward that was so heavily populatedd that its density was 1.2 million per square mile.
