{"value"=>"<p>The Statistical Bureau collected and analyzed data from federal and state muster rolls as to the height, age and nativity of U.S. soldiers, especially during the latter part of the war and the post-war period. It also conducted physiological examinations at military and other sites, as seen in materials in Series VII. Physical Examinations. Height, age and nativity records mainly comprise three types of undated materials: the forms used to collect the data, and the charts and tables used for charting and analyzing the data. The records also contain letters received 1866-1867 from regimental officers responding to Bureau circulars concerning the height or nativity of their men; these reflect the Bureau’s efforts to substantiate or augment data collected, and their interest in the impact of certain physical characteristics, such as exceptional height, on a soldier’s stamina.</p> <p>The Bureau’s investigations focused on comparing physiological characteristics across nativities and other variables such as race, and determining the representative nativities of U.S. servicemen engaged in the war. The bulk of the data collected concerns Army regiments, but data is also present for U.S. Navy sailors and landsmen. Nativities, as defined by the Statistical Bureau, can be a state, region, or country in which a soldier was born.</p> <p>Also present are miscellaneous statistical tables, including data collected at Judiciary Square Hospital and a convalescent camp.</p>"}
