On 18 May 1917 the Selective Service Act was passed authorizing the
President to increase temporarily the military establishment of the United States.
The Selective Service System was made up of 52 state (or territory) offices,
155 district boards, 1319 medical advisory boards and 4,648 local boards.
Local boards were established for each county or similar civil division in
each state, and for each 30,000 persons (approx.) in each city or county
with a population of greater than 30,000. These local boards were charged
with the registration, classification, call and training of draftees.
During World War I there were three registrations.
The first, on 5 June 1917, was for all men between the ages of 21 and 31.
The second, on 5 June 1918, registered those who attained age 21 after the
first registration (included in this was a supplemental registration held 24
August 1918 for those attaining age 21 between 5 June and 24 August 1918).
The third registration, held on 12 September 1918, was for men aged 18 through 45.
Each registration differed slightly, but the general information shown
includes: full name, date and place of birth, race, citizenship, occupation,
personal description and signature.
The World War I Draft Registration Cards consist of approximately
24,000,000 cards of men who registered for the draft in the 3 registrations.
Covering some 23% of the 1918 population of the United State, these
records are a valuable resource for genealogists.
