The reason is the height of the upper face, for which the accompanying considerable expansion of the zygomatic arches does not fully compensate. In the white groups this index ranges from approximately _50_ to _54_; it averages _52.9_ in 15 Algonquian and _53.1_ in 12 Siouan tribes. The means in the large Eskimo groupings are from a little below _54_ to a little over _55_. Its regional differences have already been mentioned. Sex differences in the index are very small. There are a number of points of significant agreement, the foremost of which is once more that in the case of Barrow and Point Barrow, and especially that of the Old Igloos near Barrow and Greenland.
