On the organizational side the decade was marked by a steady increase in membership for the "Association for Transpersonal Psychology", stabilizing at approximately 3000 members in the early nineties. In 1996 the "British Psychological Society" (the UK professional body equivalent to the APA) established a Transpersonal Psychology Section. It was co-founded by David Fontana, Ingrid Slack and Martin Treacy and was, according to Fontana, "the first Section of its kind in a Western scientific society". In the second half of the decade commentators remarked that the field of transpersonal psychology had grown steadily and rapidly.
