Credit Union Member Growth Trends, 2024–2025

According to the National Credit Union Administration (NCUA) 5300 Call Report, member growth across the U.S. credit-union system is far from uniform. Among the 3,637 credit unions with at least 1,000 members, the threshold below which a handful of new members can swing the percentage wildly, about 46% added members year-over-year, while the rest held flat or declined. The average change was close to zero, which tells the real story: growth is concentrated in a minority of institutions rather than spread evenly across the system.

Who grew fastest

Excluding tiny-base and merger artifacts, the fastest-growing sizeable credit unions added members at double-digit rates. These are genuine expansions, not statistical noise from a near-zero starting base.

What the spread means

Of the sizeable credit unions, 1,152 shrank by more than 2%, 1,536 stayed essentially flat, 604 grew between 2% and 5%, and 345 grew 5% or more. Membership growth tends to follow local employment and field-of-membership expansion, community charters in growing metros and employer-tied charters whose sponsors are hiring lead the pack, while charters serving contracting industries or shrinking regions lose members even as the national system holds steady.

Method & limitations

Figures are computed live from the credit_unions table, using the year-over-year member_growth field derived from quarterly NCUA 5300 filings (Q4 2024 → Q4 2025). We restrict the statistics to credit unions with at least 1,000 members and cap growth at 100% to exclude merger and near-zero-base artifacts. Quarterly snapshots can miss intra-year volatility and membership churn, and they cannot isolate external drivers such as local economic conditions. See our methodology for the full pipeline.
