The quick read

Unemployment is 4.2% and median household income $106,439, putting employment conditions in the middle range of published ZIP profiles.

371 housing units were authorized over the past twelve months, within 6% of the prior year — steady rather than turning.

Rent takes 22% of median household income here, below the 30% threshold conventionally called cost-burdened, and the median home is 4.8 times that income.

Each point is a separate five-year estimate, most recently $106,439 in the 2024 ACS 5-Year. Consecutive releases share four years of sample, so AreaProfile shows them as a record of successive estimates and does not compute a year-over-year change from them.

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

There are 12.5 students for every full-time teacher, fewer than in most measured places.

51.5% of students here are eligible for free or reduced-price lunch. That describes the circumstances families arrive with rather than how the schools perform, which is why AreaProfile shows it and does not score it.

Public schools only, from the NCES Common Core of Data. Schools are placed by ZIP code, so this is which schools are in this place rather than which one a particular address is zoned for — district boundaries do not follow municipal ones, and enrollment zones change. Fully virtual schools are excluded: they enroll students from across the state while reporting one administrative address, and counting them here would describe a school population this place does not have. The assessment covers grades 3 through 8, so a high school shows no proficiency figure — a dash in those columns means the test was not given at that school, not that it performed badly. Proficiency is measured against Connecticut’s own standard, so it compares cleanly within the state and only broadly against other states; AreaProfile therefore ranks it within state. The directory is current, while the proficiency figures are from the last school year with national coverage before the pandemic interrupted testing.

Housing & affordability

How it’s calculated →

Median rent of $1,919 takes 22% of median household income, below the 30% threshold at which a household is considered cost-burdened.

A median home costs 4.8 times median household income here, above the historic benchmark of about three times income.

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.

Growth & development

55/ 100
Top 42% of 5,428 published city profiles

An AreaProfile calculation combining permit volume per resident, its direction over one and three years, population change and employment growth. Permit volume alone is not the measure.

91% of recently permitted units are in buildings of five or more homes, so new supply is concentrated in apartments and condominiums rather than detached houses.

At 4.0 permitted units per 1,000 residents, building activity is above the median for measured US ZIP areas.

What this profile does not cover

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
Taxes are not published: no source covers them nationally with a method open enough to check. Cost of living now is — the index above is the Bureau of Economic Analysis price parity for this area — but it is a price level for all consumption rather than a budget for a household, its spread is driven mostly by housing, and it excludes taxes. Housing affordability is computed separately from rent, price and income, because that answers a narrower and more actionable question. 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.

Access

Airport identity, position and runway data come from the FAA. “Major airport” is an AreaProfile classification — a public-use civil airport with a paved runway of at least 8,000 feet — not an FAA hub designation. Distances are straight-line, not driving distance.
