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. THE FACTOR OF LENGTH OF RESIDENCE As we shall see also from the statistics gathered and analyzed for this volume,[102] the factor of residence “ten years or over,” with all its implications, is exceedingly important--is, in fact, the major factor in the whole situation. The indictment against the “new” immigration hangs upon it, and falls down when the term “ten years or longer” is analyzed, even in the light of the statistics presented by the Immigration Commission itself in support of the indictment. Indeed, the Commission was not entirely without compunctions on this point, and presented a table exhibiting the probability that, of the male employees from whom it derived its information, those of the “older” races had been in the United States _considerably_ longer than ten years, while those of the “newer” races had been here only _slightly_ longer than ten years. But it did not emphasize the point, and at a superficial glance this might seem a quibble; but it is of importance scarcely to be overestimated.
