How Can We Promote Zero Car Households

Today on the Streetsblog Network, a fascinating look at the top 50 "low-car cities" in the United States -- that is, cities in which a high proportion of households do not own a car at all. Human Transit's Jarrett Walker digs into a list (from Wikipedia) of the US cities with populations over 100,000 with the highest percentage of zero-car households.

New York City, unsurprisingly, ranks first, with 55.7 percent. Seattle is number 50, with 16.32. Looking at the entire list, Walker comes to the conclusion that each municipality on it has at least one of three factors in play: age (older cities were in great part designed before automobiles came into use); poverty; and/or the presence of a large university.

Walker poses an important question: for those of us who see a "low-car" future as something to strive for, what conditions need to come into play in communities without those big three factors? He writes:

So here's the question: How long will it take for a city that lacks age, poverty, or dominant universities to achieve the kind of low car ownership that these 50 demonstrate? How soon, for example, will a city be able to create a combination of density, design, and mixture of uses that yields the same performance as an old city that naturally has those features?
