Here is the 1976 Association of Unity Churches Yearbook. Members are now listed as churches, not as ministers who are leading churches. But as with earlier yearbooks, the ministers who are leading churches are listed with their churches, not as associate members. These are on pages 12 to 73.
Associate members are those not assigned to churches. This is explained on p. 74 — "Associate Members include all Licensed Teachers and Ordained Ministers, Inactive, Emeritus, or those on special assignment". So, as with earlier yearbooks, there is a substantial distinction made between those who lead churches and those who do not lead churches. Associate members are listed on pp. 74-88.
