Hi DHS,

I'm trying to merge the individual to the birth recode files for several countries using the following code in stata, where the birth recode is the "master" file:

merge m:1 v001 v002 v003 using "filename", gen(ir)

However, I'm getting a "does not uniquely identify observations in the using dataset" error. I observed duplicates in terms of v001 v002 v003 for the following files:

Mali 2001
Niger 2000
Niger 1992
Senegal 1998
Senegal 1986
Nigeria 1990

Can multiple women have the same "respondent" in the IR file? If so, how could this occur? For a few of them, I was able to find an additional identifier (such as sconces or snumber). For those surveys I can't find an additional identifier, should I be merging on caseid?

Thanks!
