ZIP 01230

What ZIP 01230 actually tells you, and what it doesn't

The 01230 ZIP Code Tabulation Area has a population of 9,095 and a median household income of $73,884. Against the other tabulation areas in this dataset, it places as follows.

The median home costs around 6.1 times what a median household here earns in a year, placing 01230 in the most expensive quarter of reporting areas. Wherever the multiple runs this far ahead of local pay, ownership is largely closed to people earning the local median, and the rental figures below matter more than the sale price.

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.

At a median age of 48.4, 01230 falls in the oldest quarter of reporting areas. Retirement destinations and long-settled rural areas cluster here, and in both the labour-force measures below cover a smaller share of residents than they would in a younger area.

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