The annual demographics were published in the April '97 e.v. Thelema Lodge Calendar. Since they rely upon known mailing addresses, the number of members falls short by 10 to 15 %. I have chosen to show the data at a world scale to show the general trend of the data rather than try to map small groups of members.
The area of the symbol shows the relative number of members per region. Thus, the United States has approximately twice as many members as in European countries combined, ten times as many as Canada.
