It should be remarked at once that inferences from these figures and others presented by the Immigration Commission require considerable discount and discrimination by reason of the fact—to which Miss Grace Abbott already has called attention[101]—that
... the numbers in the different races from whom information was secured by the Commission varied so greatly as to make it impossible to accept these conclusions as indicating the assimilability of the various national groups. For example, according to the percentages the Armenians appear to be more eager to become citizens than the North Italians or the Poles; but the comparison was made on the basis of information from 171 Armenians, 4,069 North Italians, and 10,923 Poles.

note 2: The Bohemians and Moravians are classified by the Immigration Commission with the “new” races.
This same factor of disparity in numbers operates, when a comparison of degree of assimilability is attempted, between the old and new races, with respect to residence in the United States from 5 to 9 years. The Immigration Commission gives the per cent naturalized for each race of individuals here five years. It might be expected that for this period of years conclusions could be drawn about the assimilability of the two groups of races. But here again almost six times as many individuals are classed in the new races as in the old and any general inference would be founded on insecure ground because of this disparity in numbers of cases. They, therefore, base their conclusions on the group here 10 years and over.
