ZIP 01803

What ZIP 01803 actually tells you, and what it doesn't

The 01803 ZIP Code Tabulation Area has a population of 26,004 and a median household income of $134,189. Against the other tabulation areas in this dataset, it places as follows.

The median home costs around 4.9 times what a median household here earns in a year, placing 01803 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 21% 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.

The median age of 43.9 sits above the midpoint of reporting areas, the pattern of a settled population where more residents are past child-rearing than entering it.

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