Credit union membership reached 144.7 million at the end of 2025, according to NCUA's Q4 2025 performance data — a gain of 2.4 million members over the year. On the surface, growth looks steady. Beneath it, the age profile of that membership tells a different story.
Credit union members are getting older, and younger generations are not joining at the rate their parents and grandparents did. Research from The Financial Brand shows that credit unions have been unable to connect with younger Americans as effectively as they once did, with the average member age continuing to skew above the general population. Meanwhile, 62% of credit union executives now rank new member growth among their top three concerns — up from 41% in 2022, according to CSI's 2026 Banking Priorities survey.
Where Gen Z Is Actually Going
Gen Z is not financially disengaged — they are financially active in places credit unions are not. According to Cornerstone Advisors research published in 2025, $2.15 trillion has shifted from traditional bank and credit union accounts into fintech platforms and investment apps, with Gen Z and millennials accounting for more than $1.28 trillion of those outflows. The money is moving to platforms like Robinhood, SoFi, and Cash App — not because they offer better financial products, but because they meet younger consumers where they already are: on their phones, in their social feeds, and inside the financial conversations happening on TikTok and Instagram.
Ninety-five percent of Gen Z uses mobile banking apps as their primary money management tool, according to Cornerstone. That is not a preference — it is the baseline expectation. Credit unions that still treat mobile as a secondary channel or rely on digital experiences built for desktop-first workflows are already behind.
The Fee Problem Is Worse Than You Think
Perhaps the most alarming data point for credit union leaders comes from Filene Research Institute: 31% of members under 40 say they will probably or definitely leave their credit union in the next 12 months because of a single fee they were charged. One fee. Not a pattern of poor service or a better rate elsewhere — one fee.
This is not irrational. Gen Z grew up with fee-free neobanks as their frame of reference. Chime, SoFi, and similar platforms made zero-fee banking the default experience for an entire generation. When a credit union charges a $25 overdraft fee or a $5 monthly maintenance charge, it does not just cost the institution that revenue — it costs them the member. And Cornerstone's data shows that Gen Z rates their primary checking account satisfaction at just 7.59 out of 10 — the lowest of any generation measured. The loyalty buffer is thin.
What the Cooperative Model Should Mean for Young Members
The irony is that credit unions are structurally designed to do exactly what Gen Z says it wants. Member ownership means returns flow back as better rates and lower fees. Volunteer governance means decisions are made locally, not in a distant corporate office. The not-for-profit structure means the institution's incentives are aligned with the member's — not with shareholders demanding quarterly earnings growth.
But structural advantages mean nothing if they are invisible. Most Gen Z consumers have no idea what a credit union is, how it differs from a bank, or why the cooperative model should matter to them. Filene's research has consistently found that awareness — not objection — is the primary barrier to younger membership. They are not rejecting credit unions. They have never been asked.
Credit Unions That Are Getting It Right
The institutions seeing results with younger demographics share a few common traits. They have invested in frictionless digital onboarding that can be completed entirely on a smartphone in minutes, not days. They have eliminated or restructured fee schedules that create outsized attrition risk with price-sensitive younger members. And they are meeting Gen Z on social platforms — not with corporate marketing, but with financial education content that builds trust before asking for a membership application.
Credit unions running consistent short-form video content on TikTok and Instagram Reels have seen 250% to 500% increases in website traffic and measurable gains in digital membership applications, according to Vibrant Brands' 2026 analysis. Those that have rebranded outdated checking products with transparent, modern naming conventions are seeing 8% to 12% increases in new-member conversions within months.
More than a third of Gen Z consumers told Cornerstone they would be very likely to open a new checking account if it allowed them to make investments directly, bundled credit score management, or included subscription and bill negotiation tools. The appetite is there — but it requires credit unions to think about the checking account as a platform, not a product.
The Math on Waiting
Acquiring a member under 35 leads to 2.5 to 3 times higher lifetime product adoption compared to acquiring a member over 50, according to industry benchmarking data. Every year a credit union delays its Gen Z strategy is a year of compounding opportunity cost — not just in membership numbers, but in the long-term product depth and engagement that drives cooperative sustainability.
The credit union system added 2.4 million members in 2025. The question is not whether the industry is growing. The question is whether it is growing with the generation that will determine its relevance for the next 40 years.
