Hi Tom,

thanks for your reply. I have dropped the KR wave 3 data now.

But do you also have an answer for my second question? hv001/v001, hv002/v002 and hvidx/b16 do not uniquely identify the data in wave 4 and in wave 6, independent of the country (I am using all Sub-Saharan African countries).

I am using the exact same code for wave 5 and there the merge works fine. But for wave 4 and wave 6 it does not seem to work. My code broadly looks like this:

In KR file:
rename v001 hv001
rename v002 hv002
rename b16 hvidx

In PR file:
sort hv001 hv002 hvidx
merge 1:1 hv001 hv002 hvidx using "KR.dta"

This leads to the following error message:

"variables hv001 hv002 hvidx do not uniquely
identify observations in the using data
r(459);"

Any ideas?

Best
Timo
