How does St. Johns compare to other US cities?

Household income 90% higher than other cities
Home value 37% pricier than other cities
Median rent 34% pricier than other cities

How we calculate these percentiles & ranks

Each percentile compares St. Johns against every qualifying US city; each in-state rank narrows that to Arizona only. Full formula and direction notes: methodology.
