Dauphin Island, AL population, income and ZIP codes

Dauphin Island town is a small town in Alabama, with 1,944 residents counted in the Census American Community Survey 2019-2023 ACS 5-year estimates, which places it #227 of 593 ranked by population — larger than 61% of them. The median age here is 60.9 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.

Households in Dauphin Island town earn a median of $64,615 a year, 17.7% below the national figure of $78,538 and 16% above the $55,687 median for the 322 Alabama cities we cover. 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 3.2% of residents here, less than half the 12.4% national rate.

The typical owner-occupied home in Dauphin Island town is valued at $387,400, 27.7% above the national figure and 145% above the $158,200 peer median, while median gross rent runs $1,750 a month, 24.5% above the national figure, or roughly $21,000 across a full year. A household on the local median income would put about 32.5% of gross pay toward that rent against the federal 30% cost-burden threshold, so renting here is a stretch on median earnings. The home-price-to-income ratio works out to 6×, against roughly 3.9× nationally, so buying is harder here than in the average US market. 97.9% of occupied homes are owner-occupied versus 65% nationally, an owner-dominated market where rental listings are scarce and rent medians rest on a thin sample. The rent line includes utilities paid by the tenant, a definition worth remembering when comparing it against a landlord's quoted rate.

A median age of 60.9 puts Dauphin Island town well into retirement-weighted territory, which pulls median household income down even where household wealth is high, because retirement draws are counted differently from wages.

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.
