Just did a Google. #9 is (not Stated). Question 9 is “Race of Father”. Another 9 is “Kind of Business or Industry” of the Father, also noted as a #9. It would appear that these questions are coded in transfer to a Federal type registry.
I guess like a census. What I looked at said it had something to do with population and distribution of federal funds. Guess also that could impact numbers for Representation ie: Congress?? I da know. So a 9 code is said to mean no answer was given at the time.

Ok , looked again.. Here are the reported codes.
0- Guamiam
2- White
3- Indian ( Inc. Aleuts and Eskimos)
4- Chinese
5- Japanese
6- Hawiian ( inc. part Hawiian)
7- Other
8- Filipino
9- Not Staded

Sounds kind of limited?

Those pencil codes came from the Verna K. Lee interview that Zullo recorded. As you noted, number "9" is penciled in on two boxes as seen here.

According to crazy OBots, they unequivocally say that "In 1961 "9" meant "other non-white" like it says in the coding instruction manual, but obviously, "other non-white" doesn't make any sense for box 12h “Kind of Business or Industry". Whaaaaa?

Like Zullo said, "9" means 'not-stated' where the birf certificate boxes should have been left blank.

This is the usual case of OBot CONflation. They are trying to say these internal pencil mark codes are the same as stated in classifications shown in this government publication. See the highlighted paragraph under 'Race and color' for 1961 vital statistic classifications.

And the CDC in Atlanta follow up confirmed this.

What likely happen is that the forger got hold of an image of a Hawaiian birf certificate, a template, that gave him empty boxes to fill in with the desired text.
