The United States Air Force Statistical Digest has been published each year since 1948. Over the years, while the Digest has had several changes in format, the original purpose for publishing it has not changed. The purpose has been, and will continue to be, to compile each fiscal year a single authoritative archival document providing a statistical description of the Air Force in terms of resources, organizations, and major activity parameters. Persons who require a historical description in statistical terms of each year of the Air Force's existence have found the Digest to be an invaluable addition to their information reference sources. This Fiscal Year 1992 Statistical Digest returns to an earlier format containing only actuals. Projections for the future that most always in the past have changed soon after publication have been eliminated. Tabular and graphic presentations of data have been reformatted. The United States Air Force Statistical Digest untitled "Fiscal Year 1992/1993 Estimate" published and distributed by this office in late 1992 should no longer be used as a source of any data for FY 1991, FY 1992, and FY 1993. Data for these fiscal years in this cited edition of the Statistical Digest were estimates. The latest and authoritative edition of the Statistical Digest is this edition entitled "Fiscal Year 1992" which contains only actual data and no estimates.
