Hi all,

I am attempting to merge variables from the male and female datasets onto the household dataset. The DHS help site for this ( indicates that v001 and v002 (cluster and household numbers) should be unique for the datasets. However, I am finding that these two variables do not uniquely identify all observations; there are many duplicates of these two variables in the dataset.

I also checked my variables of interest, and found that the data differs between duplicated cases. So the households are not true duplicates.

Has anyone else encountered this issue for the Zambia dataset, and have suggestions for how to successfully merge on cluster and household numbers with the household dataset?
