Oldest Old (data forthcoming)

The Oldest Old sample contains approximately 1,500 men whose ages at death are confirmed to be over 95. Researchers initially compiled a list of nearly 6,000 potential nonagenarians. The list was based upon many sources, including:

To confirm an age of over 95 at death, researchers examined the pension files for these veterans at the National Archives and Records Administration in Washington, D.C. These files usually contained detailed information on birth and death, and researchers collected the entire pension file of any veteran confirmed to be at least 95 at death. These records include detailed surgeons’ examinations and a wealth of health data. Researchers then linked these veterans to the 1850, 1860, 1870, 1880, 1900, 1910, 1920, 1930, and 1940 censuses. Because so much information is available about men who lived to late ages and because electronic indexes make linking efficient, researchers were able to achieve extremely high linkage rates.

Even though the Oldest Old sample uses familiar records, the data contain additional information from private physician affidavits and home visits by Veterans Administration representatives. These accounts provide some information on care arrangements, functional limitations (ability to walk, blindness, deafness), and mental acuity that are not generally found for younger soldiers.

A unique 10-digit identification number, stored in the variable recidnum, identifies each recruit throughout the separate data sets of the Early Indicators projects.
