The Bureau of Labor Statistics does not publish labor-force data for ZIP areas. This is the figure for Lynnfield, MA, the city containing this ZIP code.

Median rent of $2,676 takes 19% of median household income, below the 30% threshold at which a household is considered cost-burdened.

A median home costs 5.2 times median household income here, well above the historic benchmark, at a level conventionally described as seriously unaffordable.

Both affordability measures come from the same ACS release as the income they are compared with, so the comparison is like for like. They describe housing cost against local earnings and are not a cost-of-living index — transport, groceries, healthcare, insurance and taxes are not included, and a place can look affordable here and still be expensive to live in for reasons this does not capture.

5 of the twelve months have a normal average temperature between 55°F and 80°F. July averages a high of 82°F and January a low of 20°F.

Normal annual precipitation is 44.9 inches.

Air quality measures a median index of 37, in the Good band, and about 4 days a year pass 100, the threshold at which the air is unhealthy for sensitive groups.

Climate figures are thirty-year normals, not current conditions. They describe what a typical year looks like rather than what the weather is doing today. Air quality is measured rather than modelled, by EPA monitors, and published by county only where a monitor sits — roughly half the counties AreaProfile publishes have one, and the rest show nothing rather than an estimate. Air masses are regional, so a county reading describes the air over a place reasonably well, but it is still the county reading.

Three things people look for are missing from every AreaProfile page, and each is missing for a reason rather than by oversight. The Area Score is calculated without them and the weighting is documented on the methodology page.

Reported crime

Offences reported to police are published by department rather than by town, and only where a department reported every month of the year. No municipal department reports for this place — many smaller communities are policed by the county — so there is no figure to show. A partial year is never scaled up to look complete, and arrest counts or news volume are never substituted for it.

Taxes and full cost of living

No public source publishes either with national coverage and a method open enough to check. Housing affordability above is computed from published rent, price and income, and excludes transport, groceries, healthcare, insurance and taxes — commuting cost in particular tends to offset suburban housing savings. Nothing here is individualised tax advice.

Anything about a specific address

Every figure describes an area, not a street or a house. School attendance zones, insurance pricing and the character of a neighbourhood all vary within the places measured here.

How this ZIP area compares with Lynnfield as a whole. Both figures come from the same ACS release, so the comparison is like for like.

Some demographic statistics use Census ZIP Code Tabulation Areas, which approximate but do not exactly match USPS ZIP delivery geography. See the methodology for how AreaProfile maps between them.
