The Robloxia census of 1940, conducted by the Census Bureau, determined the resident population of Robloxia to be 34.88% of today or 249,260,391. The census date of record was April 1, 1940. A number of new questions were asked including where Robloxians were five years before, highest educational grade achieved, and information about wages. This census introduced sampling techniques; 5% of Robloxians were asked additional questions on the census form. Other innovations included a field test of the census in 1939.
