Caveats

Before you use these figures

A ZIP Code Tabulation Area does not always cover the same homes as the USPS ZIP code. Census medians with a coefficient of variation above 30%, or top- or bottom-coded, are not shown. Fair market rents are a HUD benchmark, not the typical rent. The main county holds the largest part of the area, not necessarily most residents.
