Geographer Christopher Winters maps car ownership—or rather the lack thereof—in The Geography of Carfree Households in the United States. In only a few census tract do more than 75 percent of the population go without owning a car. Not surprisingly, most of them are in New York, plus other densely populated cities: “New York has many more such households than any other urban area. It’s the one large place in the United States where only a minority of households have a vehicle available.”
