The Citadel Military College dataset comprises height data for 6,534 applicants, taken upon their medical examinations. Although problems of selectivity may arise due to the self-selection of the applicants, their economic backgrounds are relatively diverse (Coclanis and Komlos 1995). The regional scope of the dataset covers many US states, but more than half are from South Carolina. It includes birth decades between 1860s and 1930s. All cadets were between the ages of 14 and 26 at the time of each survey, meaning that some were still growing at the time of their medical examinations. The original measurements were taken in British inches.
