Following is a response from Senior DHS staff member, Tom Pullum:
I used the following Stata code to check whether there are any discrepancies between the v20* variables and the b4* and b5* variables in terms of the numbers of sons and daughters who are alive or dead. I get perfect agreement. I used b5 rather than b7, but b5 and b7 should agree, in that b7 is <. If the child died (b5=0). However, b7=. could mean either that the child survived (b5=0) or there was no birth for the specified value of bidx (b5=.) Can you check again?
use v20* b4* b5* using "...IAIR52FL.dta", clear
rename *_0* *_*
gen v20sons_alive=v202+v204
