Using data from the Census Bureau, TransUnion and the Federal Reserve, the study’s authors looked at inflation-adjusted household debt in the country’s largest 181 cities found Santa Clarita, California to have the highest average household credit card debt ($21,836), followed by Chula Vista, CA ($20,920), New York, NY ($19,207), Fontana, CA ($18,843) and Rancho Cucamonga, CA ($18,549).
Nope, the $63 billion figure is just sheer population, given that the average household debt is laid out right there at the top. It should be noted New York also has a very high per capita income compared to most other large cities, and this Wallethub “study” doesn’t adjust for purchasing power parity
