Until 1993, "membership" of the CBA was limited to societies and organisations. Today there are over 600 institutional members, which range from village archaeological groups to museums, county societies, universities, commercial archaeological units and national bodies. Individual membership has climbed steadily since its introduction in 1993, and now exceeds 6,000. Through the eleven English Regional Groups, CBA Wales/Cymru and the Council for Scottish Archaeology (all of which have individual membership), the CBA provides a unique forum for the British archaeological community, and the public beyond.
