I’m around Barry’s age, and was born in NYS. And even accounting for the difference in states, size of the municipalities, and hospitals, my BC doesn’t look anything like that COLB. FWIW.
Look, I was born in North Carolina in 1964, and my birth certificate was hand written (not typed). It differs from state to state.
I'm five years younger than Obama, and was born in Mississippi, and my old microfiche long form looks very similar to the Obama long form document. Even the verbiage in many places is identical. Block 12b on the HI form and block 11b on the MS form both say "Kind of Business or Industry". Verbiage in HI block 6c is identical to MS block 1c. HI blocks 3 and 4 are identical to MS blocks 5a and 5b.
The Mississippi form does have some more information, such as previous pregnancies by the mother, length of pregnancy, birth weight, and if the mother is married. The Mississippi document does not have a place for occupation of mother, nor birth hour.
