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.

We know that educational attainment is probably the single biggest determinant of urban economic success. If you're hoping to predict average household incomes, looking at the percentage of the population with a 4-year college degree is a pretty good place to start. But let's take this a step further: to what extent does graduating from an elite university affect both pay and performance?

It turns out, according to this recent study, that the pedigree of one's university isn't all that good at predicting motivation and talent. It does, however, impact pay. Average early career salaries for graduates of the top 10 colleges in the US are almost 50% higher than those with degrees from the ten colleges within the City University New York school system. This is according to data from Payscale and the US Department of Education.

But this pay delta doesn't necessarily match the performance delta that you might expect. The study found that for every 1,000 positions that you move in Webometrics' global university ranking (which is what they used for their research), overall performance only changes by about 1.9%. In other words, a graduate from the alleged number one university is only going to perform, on average, about 1.9% better than someone from the 1,000th best school.

I'm not exactly sure how to practically interpret a 1.9% improvement in performance. But 2% compounding on 2% each year should get you somewhere. Regardless, graduates from top universities do generally score higher on competency examinations. The reasoning behind this is thought to be at least twofold: 1) more selective admissions create a better pool of students and 2) top universities should provide better training.

Whether that's enough to justify the higher pay is a separate discussion. But if you're looking to measure urban economic success, the data does suggest that elite universities should lead to overall higher average incomes.

I just came across this chart from Axios, which relies on data from the Federal Reserve Bank of St. Louis and the Kaiser Family Foundation. It compares median household income against the average cost of employer health insurance (in the United States).

What it is saying is that, after adjusting for inflation, the median household income has only increased by 2% from 1999 to 2017, whereas employer health insurance costs have increased by some 121% over this same time period.

The takeaway: Rising healthcare costs are believed to be eating away at take-home pay in the US. As of 2017, health insurance costs were estimated to represent about 30% of the average household income. That feels like a big number to me.
