A lottery drawing – the first since 1942 – was held on December 1, 1969, at Selective Service National Headquarters in Washington, D.C. This event determined the order of call for induction during calendar year 1970; that is, for registrants born between January 1, 1944, and December 31, 1950.
The various exemptions which draft-eligible men could use to avoid service, such as still being in university education or being medically unfit, were thought to allow better-connected and middle class men to evade the draft more easily than working class or minority men.
All men of draft age (born January 1, 1944, to December 31, 1950) who shared a birthday would be called to serve at once. The first 195 birthdays drawn were later called to serve in the order they were drawn; the last of these was September 24.

Conscription in Vietnam has existed since 1975 and requires male citizens between the ages of 18 and 25 (18 to 27 for those who attend colleges or universities) to perform compulsory military service. Women are not required to perform military service, but they may voluntarily join the military.
The large cohort of Baby Boomers and late Silent Generationers allowed for a steep increase in the number of exemptions and deferments, especially for college and graduate students. More than half of the 27 million men eligible for the draft during the Vietnam War were deferred, exempted or disqualified.
Certain elected officials, exempt so long as they continue to hold office. Veterans, generally exempt from service in peacetime draft. Immigrants and dual nationals in some cases may be exempt from U.S. military service depending upon their place of residence and country of citizenship.
Although the Selective Service's deferment system meant that men of lower socioeconomic standing were most likely to be sent to the front lines, no one was completely safe from the draft. Almost every American was either eligible to go to war or knew someone who was.
In the early 1960s, nearly all 18 to 26-year-old male U.S. citizens and most noncitizens living were required to register for the draft.
