Nope, not what I meant.  It just isn't possible to compare census counts for native Hawaiians across changes in how ethnicity is determined.  So, your comparison of the low census numbers a long time ago with the high census numbers recently is influenced by the change in determination method, and is not an accurate indication of actual changes in the native Hawaiian population.

Bob Schmitt was unhappy with the change in determination method for just this reason.  He wanted comparisons like the one you attempted to be meaningful.  Unfortunately, they are not.
