ZIP 01840

What ZIP 01840 actually tells you, and what it doesn't

The 01840 ZIP Code Tabulation Area has a population of 6,977 and a median household income of $30,696. Against the other tabulation areas in this dataset, it places as follows.

Rent absorbs roughly 42% of median household income, among the highest quarter of reporting areas. Because renter households usually earn below the area-wide median, the burden on actual renters runs higher than this ratio shows.

Half the residents are under 34.9, young enough to place 01840 in the youngest quarter of the 32,853 areas reporting an age. Campuses, barracks, and dense rental districts dominate this end of the range, and where that is the cause the income and poverty figures describe students rather than settled households.

The ACS publishes no median home value for 01840. Those rows read "Not reported" below rather than zero; a suppressed estimate is not a measurement of nothing. Small resident counts are the usual reason the Bureau withholds one.

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