11549 — Uniondale, New York

72% of adults hold a four-year degree, higher than 97% of measured US ZIP areas.

6 of the twelve months have a normal average temperature between 55°F and 80°F. July averages a high of 83°F and January a low of 25°F.

Normal annual precipitation is 38.3 inches.

Air quality measures a median index of 31, in the Good band, and no day in the year passed 100.

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 modeled, by EPA monitors, and published by county only where a monitor sits — a little over half the counties AreaProfile publishes have one, and about a fifth of all US counties do, 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.

Some things people look for are not on this page, and each is absent 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

Offenses reported to police are published by department rather than by town, so AreaProfile shows a rate only on city profiles, and only where that city’s department submitted every month of a year. Any cities listed on this page carry their own figure where their department reported a full year. 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 individualized 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 neighborhood all vary within the places measured here.

Profile recalculated August 30, 2026. Recalculation is not the same as new source data — each figure above shows the period its source actually covers. Read the full methodology or browse every source.

How this ZIP area compares with Uniondale 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.
