Are credit union deposits insured?

Federally insured credit unions are covered by the NCUA Share Insurance Fund to $250,000 per member, per ownership category.

How to read the credit unions in Lewiston numbers

Start with one distinction: what we publish for Lewiston, ME are medians, not averages.

A median is the midpoint: half of the local market sits above it and half below. Averages get dragged around by a handful of extreme values — one very expensive property, one unusually large loan, one graduate earning far more than their classmates — so a median is the safer number to plan against. Locations on record of 8 and institutions represented of 8.

Use them to frame picking a branch or an institution to bank with rather than to settle it. Your circumstances — credit, timing, the specific offer in front of you — move the outcome more than the local midpoint does.

What these numbers mean for people choosing where to open an account

Context does most of the work here. A number is only high or low next to something else, so we publish Lewiston, ME and how it sits inside Maine against a wider benchmark on the same measure. State of Maine.

Small gaps tell you nothing — sampling error alone can produce them. Large gaps almost always have a physical cause: the age of the housing stock, commuting distance, the balance between renters and owners, or a single large employer setting local pay.

That is why a single figure should never carry a decision on its own. Read two or three measures together — what comes in, what housing costs, what is left — and the picture stops being ambiguous.

A short checklist before you act

None of this needs a spreadsheet. It needs the discipline of checking the same handful of things every time, whether you are picking a branch or an institution to bank with for the first time or the fifth.

  • Verify the branch is still open and staffed before you travel; registers lag closures by a quarter or more.
  • Check whether deposit insurance covers your full balance, and how joint accounts change that limit.
  • Ask what the number looks like in a bad year, not an average one, and make sure the plan still holds.
  • Write down the monthly number you can genuinely cover, not the maximum a lender or admissions office says you qualify for.
  • Compare at least three offers. Pricing on the same product varies more between providers than most people expect, and the gap is yours to keep.
  • Check the fee schedule and the fine print, not the headline rate — that is where the real cost usually hides.

How Lewiston, ME compares

Comparison is the fastest way to tell a genuinely unusual local market from an ordinary one. We benchmark Lewiston, ME against Maine and against the national picture on the same definitions, in the same period, so the difference you see is a real difference rather than an artefact of two datasets disagreeing.

Definitions matter as much as the numbers. Two sources can both publish a "median rent" and mean different things — one including utilities, one not; one covering every unit, one only those recently let. Mixing them produces gaps that look meaningful and are not.

Any measure the source flags as unreliable is dropped rather than smoothed. That is why some pages carry fewer figures than others: the local market itself is thinly sampled.

Common questions

How current is the credit unions in Lewiston data?

The figures come from the most recent release of the FDIC office file and the NCUA credit union branch file, and we refresh the page when a new one is published. Public datasets run a reporting lag of several months to two years, so the latest available period is not the same as today.

Why does another site show a different number for Lewiston, ME?

Almost always because it is measuring something slightly different, or using an earlier release. Check the definition and the period before assuming one of the two is wrong; federal branch and office registers publish several near-identical measures with meaningfully different scopes.

Can I use this for picking a branch or an institution to bank with?

As a benchmark, yes — it tells you whether an offer or an asking price is normal for this local market. As a substitute for your own quote or estimate, no. Locations on record of 8.

Sources, method and limits

The page is assembled from federal branch and office registers, specifically the FDIC office file and the NCUA credit union branch file. Nothing here is modelled from a proprietary black box: every figure traces to a published record, and where we derive a ratio we show both inputs so the arithmetic can be checked.

The limits are the usual three: sampling error grows as geography shrinks, published data always trails reality by months or years, and a midpoint says nothing about the extremes at either end of the local market.

Where a source revises a figure, the revised value replaces the old one rather than sitting alongside it, so the page always reflects the current official position. If you spot a number that looks wrong, it is worth telling us — corrections get made against the source record, not by guesswork.
