ZIP code 06605

ZIP 06605 is a small city in Fairfield County, Connecticut, with 25,238 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #48 of 288 ranked by population — larger than 83% of them. The median age here is 33.6 years against 39.1 nationally, a slightly younger profile than the country as a whole. Places under 65,000 residents only appear in the five-year release, never the one-year file, so these values pool sixty months of responses and lag the current year by design.

Households in ZIP 06605 earn a median of $59,673 a year, 24% below the national figure of $78,538. This figure covers the household, not the worker: two people on ordinary wages at one address outrank a single professional in the same table. Poverty reaches 24.5% of residents here, well above the 12.4% national rate, which is the single clearest signal in this dataset that median income here is carried by a narrow band of households.

The typical owner-occupied home in ZIP 06605 is valued at $273,100, 10% below the national figure, while median gross rent runs $1,423 a month, 1.2% above the national figure, or roughly $17,076 across a full year. A household on the local median income would put about 28.6% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is within the standard affordability guideline. The home-price-to-income ratio works out to 4.6×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 30% of occupied homes are owner-occupied versus 65% nationally, a renter-majority market, so rent figures matter more here than the home-value line. Gross rent folds in the utilities a tenant pays separately, so it is closer to the real monthly outlay than a headline rent figure.

No figure on this page is estimated by us; each one comes straight from the published ACS tables for this area. Small-area estimates still carry wider margins of error than state or national figures, so check the linked ACS tables before relying on them for lending, appraisal or legal work.

ZIP 06605 is tabulated inside Fairfield County, Connecticut, one of 46 ZIP areas the Census publishes for that county and 288 across Connecticut. This is a mid-sized suburban ZIP inside a county that is split across many delivery areas. 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 06605 can be handled by a post office in a neighbouring county even though the tabulation area is filed here.

Against its own county, 06605 reports a median household income of $59,673, 57% below the $137,778 county median, and 44% below the $105,813 typical CT ZIP. Owner-occupied homes are valued at a median of $273,100, 49% below the county figure and 22% below the statewide ZIP median. Rent is reported gross — the contract amount plus tenant-paid utilities — at $1,423 a month, which is why it reads higher than the advertised rent on a listing for the same unit.

A taxable purchase made inside 06605 carries 6.35% at the register, assembled from the Bridgeport jurisdiction stack: the Connecticut state rate plus every county, municipal and special district levy that reaches this address. Because those district boundaries were drawn for schools, transit and hospital funding rather than for mail delivery, two addresses inside 06605 can legitimately fall under different totals — the rate shown here is the one that applies to the dominant jurisdiction.

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 06605 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.
