How to read the credit unions in Butte numbers

Every figure on this page for Butte, MT is a median, not an average, which matters more than it sounds.

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 10 and institutions represented of 9.

They describe the middle of the market, so they are a starting point for picking a branch or an institution to bank with and nothing more. Anyone quoting you a number will be pricing your file, not the median.

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 Butte, MT and how it sits inside Montana against a wider benchmark on the same measure. State of Montana.

A difference of a few percent is inside the survey's own margin of error. A difference of a quarter or more is real, and it normally reflects the housing mix, the dominant local industries, or how much of the population is retired rather than working.

The useful habit is to pair every figure with the cost it has to cover. Income against rent, loan size against income, price against what the same money buys one county over.

Where Butte, MT sits against the wider market

Comparison is the fastest way to tell a genuinely unusual local market from an ordinary one. We benchmark Butte, MT against Montana 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.

Most contradictory statistics you meet online are definition mismatches rather than errors. Gross versus net, occupied versus advertised, applications versus originations: each pair produces a different headline from the same underlying reality.

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.

What to check before you commit

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.
  • 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.
  • Ask what the number looks like in a bad year, not an average one, and make sure the plan still holds.

Frequently asked questions about Butte, MT

How current is the credit unions in Butte 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 Butte, MT?

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 10.

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.

Be aware of what the data cannot do. Small-area estimates are noisier than headline national ones, every source reports on a delay, and no median describes the outliers that people most often remember.

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.
