ZIP code 01937

ZIP 01937 is a very small community in Essex County, Massachusetts, with 146 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #518 of 539 ranked by population — larger than 3% of them. The median age here is 53.6 years against 39.1 nationally, a markedly older profile that usually tracks retirees staying put and younger households leaving for work. At this population the ACS sample is small, so the margin of error around every dollar figure below is wide — treat the numbers as a band, not a point, and expect them to move between annual releases without the place itself changing.

Household income here is measured before tax and pooled across everyone at the address, which is why it reads higher than typical individual earnings in the same area.

The Census withheld household income, home value, gross rent for ZIP 01937 because the sample was too thin to publish at this geography. Those values were suppressed at the source, not lost in our dataset, and we do not model a replacement. Everything else on this page comes straight from the ACS 2019-2023 ACS 5-year tables.

ZIP 01937 is tabulated inside Essex County, Massachusetts, one of 44 ZIP areas the Census publishes for that county and 539 across Massachusetts. This is one of the smallest tabulated ZIP areas in the state, the kind of rural route where a single subdivision or farm cluster accounts for most addresses. County assignment on this page follows the largest share of the ZIP's land area, which matters where a delivery route crosses a county line: mail addressed to 01937 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Massachusetts charges 6.25% statewide, and no local sales tax is layered on top, so the state rate is the full amount collected in 01937.

Everything above comes from the Census Bureau American Community Survey 2019-2023 ACS 5-year estimates for this ZIP Code Tabulation Area, with sales tax rates traced to the state revenue agency. Five-year estimates pool sixty months of responses, so they are stable enough to compare 01937 with its neighbours but always trail the current year, and any value the Census suppressed for sample size is shown as unpublished rather than filled in with a model.
