Data Samples Overview
The principal accomplishment of the Early Indicators project has been the creation of a data set to study the process of aging longitudinally in the Union Army (UA) cohort - a white, northern population that reached age 65 mainly between 1885 and 1912. The data set is comprised of 15,000 variables on each of over 39,000 recruits.
Project staff has also completed a USCT sample of the life histories of approximately 6,000 recruits in USCT regiments. This sample was the only one that covers the life histories of the first cohort of African Americans to reach age 65 in the 20th Century and will remain an invaluable tool for researchers for years to come. The Expanded USCT sample of 15,000 USCT veterans is also available.
Additional samples were collected to extend coverage of certain interesting populations. The Andersonville sample targets survivors of the war's most infamous prison camp and can be used to look at the later life effects of traumatic hardship. The Oldest Old sample, composed entirely of veterans who lived to over 95 years of age, can be used to examine the factors that contribute to extremely long life. The Urban sample focuses on recruits enlisted from the largest U.S. cities at the time, giving a sample to study the health effects of the urban population during a period of rapid urbanization.
