The category "white" includes, in addition to persons reported as "white," those reported as Mexican or Puerto Rican. With one exception, a reported mixture of Negro with any other race is included in the Negro group; other mixed parentage is classified according to the race of the nonwhite parent and mixtures of nonwhite races to the race of the father. The exception refers to a mixture of Hawaiian and any other race, which is classified as Part-Hawaiian.
In most tables a less detailed classification of "white" and "nonwhite" is used.
Now we know the government is a stickler for codes so that big brother can keep track of all our statistics. Well, according the the US CDC website there have been some revisions as of late to the types of codes for 'race' on vital records certificates.
Prior to 2009, the latest revision to the actual long form took place in 2004. In 1961, a black person was listed as either 'black' or 'negro'. In 2004, the one showing on the CDC site shows he could have been listed as either 'black' or 'African American' as ethnicity then came into play. Now in 2009 (revised 1/09), codes for those of the Negro race are listed and one can now be listed as just 'African' as is shown on Obama's COLB.
US vital statistic birth records for 1961 in Hawaii (By place Of residence. Data refer only to births occurring within the United States. Based on a 50-percent sample.

On page 205 are the statistics for Live Births, non-White Hawaiian births:
• 50 -- attended out of a hospital by physician or midwife
So, that's around 76 unattended births in the year Obama was born. Was Barack Obama one of those 76? Information regarding these birth came from the word or statement of a relative. It might account for the Obama/Nordyke birth certificate numbers anomaly.
