Following is a response from Senior DHS Stata Specialist, Tom Pullum:

You are getting a large number of unmatched cases because you do not have any restrictions on age. The cases with _merge=1 are household members who do not appear in the birth histories--obviously the great majority of household members. The cases with _merge=2 are "children" in the birth histories who can be up to 30-34 years old, and not in the same household as their mother. If the child is missing on b16, it is because he/she has died. If b16 is =, then the child is living but not in the household.

It would be reasonable to impose an age limit such as 4 or 14 or 17 and to omit children who have died.

I don't see anything wrong with your Stata code.
