The overall growth rate in credit union membership declined 0.1% during the year ending during the second quarter. Membership was unchanged at the median over the previous year.

However, 75% of the credit unions with declining membership had assets of $50 million or less.

Some 50.3% of federally-insured credit unions reported having fewer members at the end of the second quarter of the year. The highest growth rate was in Washington State at 2.7%; the lowest was in Pennsylvania, where membership dropped 1.4%.

Shares and deposits rose in every state over the year ending in the second quarter. And across the country, 80% of federally-insured credit unions had positive net income during the first half of the year, a slight increase from 79% during the period last year.

Nationally, the median growth rate in shares and deposits was 4.1%, up from 3.3% a year earlier. The growth rate was the highest in Idaho, at 9.8%, while the growth rate was the lowest in Washington, D.C., with 1.1% growth.
