Membership reach. South Dakota credit unions report about 38 memberships for every 100 residents, vs 43 nationally — a rough measure of how deeply credit unions reach the population. (This counts memberships, not unique people: one person can belong to more than one credit union, and large South Dakota credit unions serve members in other states, so it overstates true in-state penetration.)

Method. Compiled from public NCUA 5300 Call Report data (Q1 2026), covering federally insured credit unions headquartered in South Dakota that filed for the quarter. System totals are exact sums; ratios and growth are the median credit union in each place, computed through the same disclosed equations used across CUNinjas (a credit union that branches across state lines is counted only in its home state). Cells for a group of fewer than three credit unions are withheld. Population figures are U.S. Census Bureau Vintage 2024 estimates. Not affiliated with the NCUA.
