ZIP 01240

What ZIP 01240 actually tells you, and what it doesn't

The 01240 ZIP Code Tabulation Area has a population of 4,922 and a median household income of $82,578. Against the other tabulation areas in this dataset, it places as follows.

The median home costs around 5.1 times what a median household here earns in a year, placing 01240 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.

At the median, rent consumes roughly 16% of a median household's income -- below the midpoint for reporting areas, and well under the 30% line commonly used to define a cost burden.

At a median age of 58.1, 01240 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.
