No, the claim that can't be backed up is that the alleged instruction manual was used to classify births in 1961. The 1961 Natality Report shows otherwise. It's posted at the CDC website. The racial classifications in that report are not the same as the alleged coding manual.
It says right on the manual that it was for classifying births that took place in 1961, doofus.
As for "alleged," it's obvious that it's the real and correct manual. Aside from which, IT WAS PRODUCED BY A FREEPER.

A link to the report, Sherlock. And the exact page number on which your alleged conflict is to be found and can be confirmed.
Otherwise, you claim is bulls**t.
