World War I Census Records
The 1920 Census did not ask any questions specific to military service. However, the 1930 and 1940 U.S. Federal Censuses did ask questions about veterans that may indicate service in WWI.

1930 U.S. Federal Census
The 1930 Federal Census (NARA T626), asked if a person was "A veteran of the U.S. military or naval forces mobilized for any war or expedition" and "What war or expedition" they served in.

1940 U.S. Federal Census
The 1940 Federal Census, asked "Is this person a veteran of the United States military forces or the wife, widow, or under 18-year-old child of a veteran?" and "If child, is veteran-father dead?" and "War or Military" served in. These were only asked of persons which were recorded on line 14 and line 29 of the census, which would have covered about five percent of the population.
