The committee reiterates that the more detailed AAS membership breakdown by field and discipline was done for U.S. members only.

Note also that AAS membership varies with time during the year as membership renewals arrive. The bulk of the membership renews by the January 1 start of the membership year; however, new memberships and renewals come in throughout the rest of the year. Until 1993, the membership numbers are those quoted for the end of the year in the Executive Office report for the January meeting. Starting in 1994, membership totals are reported at the June meeting of the society, so some of the decline between 1993 and 1994 represents the reporting date. Almost all members renew by the June meeting.
