Here's further evidence that New York City is unlike any other city in the US. According to survey data from the US Census Bureau ( via Bloomberg ), New York is the only city in the US where the majority of households do not have a car, van, or truck. As of 2024, the figure was 56.7%.
Also noteworthy is the fact that the next two cities on the list — Jersey City and Union City — are just across the Hudson River. So they are highly connected to New York both geographically and economically.
The above chart also includes the median household income for each city. Income is a factor when it comes to car ownership, but I don't think it's the strongest predictor. Some of the highest zero-vehicle cities on this list also have some of the highest median incomes — places like DC, San Francisco, and Cambridge.
The strongest predictor is built form. Once again, urban density, transit access, and a mix of uses are how you give people the option of not driving.
