Key findings

Community banks and credit unions under $10 billion in assets operate 45,434 offices across the 50 states and D.C. The counties around those offices are 20.1% age 65 and older, against 18.9% for the country as a whole.

The densest older footprints are in Maine (24.9%), Vermont (24.6%), and Delaware and New Hampshire (both 23.9%). Hawaii and Montana follow at 22.9%.

The largest absolute numbers sit elsewhere. We estimate that California credit unions serve about 1.8 million members 65 and older, followed by Texas (1.3 million) and Florida (1.3 million). Across all states the estimate is about 20 million, out of 105 million members.

The lightest older footprints are in Utah (13.4%), District of Columbia (13.6%) and Texas (16.7%). Even there, older customers are a large group in absolute terms.

This report measures where older residents live near community institutions. It does not measure fraud losses, and it says nothing about any one institution.

Why older customers matter for fraud teams

Two federal findings frame how teams think about elder financial exploitation. FinCEN's April 2024 analysis found that about four in five elder exploitation filings involve strangers and about one in five involve someone the victim knows. The CFPB's February 2019 report on suspicious activity reports found that when the older adult knew the suspect, the average loss was about $50,000, compared with about $17,000 when the suspect was a stranger.

Both matter. Strangers account for most filings. Known-person cases are fewer and each one costs more. Staff at a community institution often see both kinds across the same counter.

Method and sources

Institutions in scope
3,768 FDIC-insured community banks (FDIC's community bank flag) under $10 billion in assets, and 4,263 federally insured credit unions under $10 billion in assets. All are headquartered in a state or D.C.
Offices
24,724 bank offices from the FDIC BankFind locations file and 20,710 credit union offices from NCUA's branch information file. Main offices and branches both count. Each office is placed in its county.
Older share of the footprint
For each office we take the share of county residents who are 65 and older (Census Bureau Vintage 2025 county estimates, July 1, 2025). We average that share across offices in a state. This is a measure of where offices sit. It is not the age mix of customers.
Estimated older members
For each credit union we split its reported membership evenly across its offices, then multiply each office's share by its county's 65+ share. We add the results by state of office. This assumes members mirror the age mix of the county and live near the office where we count them. Treat the numbers as rough. We make no estimate for banks.
Ranking
The main ranking uses the office-weighted 65+ share. It favors places where older residents are a large part of the local population. A second rank, by estimated older credit union members, shows where the largest absolute numbers are.

Limits
County age mix is not customer age mix. Online and out-of-county members are not captured. Some offices are shared or limited-service. 19 offices (0.0%) could not be matched to a county and are left out of the age averages. Connecticut counties were replaced by planning regions in the Census data, and we matched each office to its region. Small states have few institutions, so one institution can move their numbers. Call Report and BankFind data change every quarter. Individual institutions are not scored or named in this report.

What institutions can do

None of this requires new software. Most of it is process.

Look at your own footprint first. Pull the 65+ share for the counties your offices serve and compare it with the state figure above. Branches in older counties may need more training time and a faster escalation path.

Train for both patterns. Strangers show up as urgent wires, gift cards, crypto purchases and sudden changes in routine. Known-person cases show up as a new signer, a power of attorney agent moving money, or a household member who answers for the customer. Tellers see different signs in each.

Ask for a trusted contact. Many customers will name one if asked at account opening or at a routine visit. It gives you someone to call when something looks off.

Write down a hold-and-escalate path. Staff should know who to call, what they can pause, and when to bring in the BSA officer, without waiting for a manager to be found.

Use the FinCEN elder financial exploitation key term in SAR narratives so the filings can be found and counted. Keep a current contact for your county's Adult Protective Services, and for local law enforcement who handle financial crimes.

Review the cases you already have. Count how many involved a known person and how many a stranger, and see whether your own mix looks like the national one.
