I am trying to establish the time trends of child mortality (infant and child) among first born in Tanzania.
Why do I find differences in value between:
(a) A variable indicating 'maternal age at first birth' (directly from the data set: (V212) AND
(b) Year the first child were born - Year the mother was born) (B2$01-V010) = Age of the mother at first birth
Then, what is the 'near' correct age at birth of the 'FIRST BORN'?
Also, aiming to use first born,I think BIDX$01 refers to the FIRST birth and BORDX$01 is similar to BIDX0$? (in the reverse order).
So, looking for the first birth, I should concentrate preferably with BIDX$01. Am I correct??
