Reading this Connecticut list

What the Connecticut numbers actually show.

Connecticut is unusually decentralised. No single centre dominates — the ten largest ZIP codes together hold just 15% of the 3,598,348 residents here, and 125 separate entries clear 10,000 people. State-level averages are more representative here than in most states, because there is no outsized core pulling them. Half of these ZIP codes hold more than 7,984 residents, which is a small-town scale: big enough for published estimates, small enough that one employer or one subdivision moves the numbers.

Buying is a little easier here than nationally: Connecticut's median ZIP code shows $348,800 in home value on $105,813 of income, a ratio of 3.3 against 3.9 across the country. Rent stays modest against earnings — $1,432 a month, roughly 16% of median household income over a year.

Incomes fan out sharply inside Connecticut. Strip the outliers and the top-decile ZIP code still earns 2.63× the bottom-decile one ($158,357 against $60,224); include them and 06820 tops the list at $250,001 and 06702 anchors the bottom at $16,198. A single "Connecticut average" is averaging across two different economies.

Coverage is close to complete: only 18 of 288 rows show a blank where the Census suppressed an estimate for sample-size reasons. The rest are published five-year values, averaged over sixty months of responses.

Questions people ask

Specific to Connecticut.

How many ZIP codes does Connecticut have? 288 appear in the current federal tabulation. ZIP code tabulation areas are the Census approximation of postal ZIP codes, so the count differs slightly from the number of ZIPs the Postal Service delivers to in Connecticut, and PO-box-only ZIPs have no area at all.

Which Connecticut row should I compare mine against? Pick ZIP codes within roughly the same population band. In a state this spread out, size drives the housing and income figures more than region does.

How current is this? Every figure comes from the American Community Survey 2019-2023 ACS 5-year release published by the US Census Bureau, ACS 2019-2023 5-year estimates. It reflects the full survey window rather than a single date, and it is the most recent vintage available for ZIP codes this small.
