In 2000, a study by Alexei D. Krindatch, of the Patriarch Athenagoras Orthodox Institute, presented a substantially lower figure-115,100 adherents (baptized Orthodox who attend services on at least an occasional basis and their children) and 39,400 full members (persons older than 18, paying annual Church membership fees).
In 2004, Jonathan Ivanoff stated in a presentation at the OCA's Evangelization Conference that the Church's census population in 2004 was 27,169, and that membership from 1990-2000 declined 13 percent.
