That is what I’m thinking: It is the 47,044th Certificate Copy of Registration of Birth issued since 10 December 1963. I researched it and found it consistent with the rate of population growth during that time. Subtract natural deaths, add in high infant mortality rate incl. some registered births, and subtract non-registered births and the number is still consistent.
That is not a zero. Compare it to the name Obama on the cert and you’ll see it’s an “O” It looks like that is a reference to the 44B location in the registry referenced at the bottom. O likely means it’s categorized by his last name and the 47 could be a number of things.
This has been discussed ad nauseum today :)
