While the USAF Statistical Digests and Summaries are not AF History publications, the information they contain is valuable and often requested by researchers.  The statistical data has been collected, compiled and produced since 1945 by the Comptroller of the Air Force.  

Earlier Digests contained a wealth of information about the USAF. Some include organization charts, leadership lists, lineage of commands, installation maps, chronologies, etc.

Be aware that categories of statistics may change, as well as the starting date of the fiscal years. Categories may be dropped, added, combined with others and may vary in methods of calculation throughout the years.  

Many of the electronic files were produced by manually cutting apart and scanning existing documents. Quality varies. AF Historical Support Division does not have a Digest/Summary for all years.

2013 is the last year that the Statistical Digest was published.
