ZIP 37931

What ZIP 37931 actually tells you, and what it doesn't

The 37931 ZIP Code Tabulation Area has a population of 30,463 and a median household income of $90,247. Against the other tabulation areas in this dataset, it places as follows.

The median home is priced at about 3.2 times median household income, above the midpoint for reporting areas. A gap of this size usually means demand is being set by buyers whose income is not counted in this ZCTA -- commuters, second-home buyers, or investors.

Median rent works out to about 18% of median household income, above the midpoint for reporting areas though still short of the 30% cost-burden line. Note that this compares two medians, not the same households: renters here typically earn less than the ZCTA-wide median, so their real share is higher.

A median age of 37.9 is on the younger side of the reporting range -- the profile of an area still taking in households at the family-forming stage rather than one that has finished doing so.

ZCTAs approximate USPS ZIP codes rather than matching them, and these are 5-year ACS estimates, so they trail current conditions.
