Following is a response from DHS staff member, Tom Pullum:

The computer commands will depend on what statistical package you are using. In Stata, this is done with the "append" command, not with "merge". There have been other posts on appending data files and you can search for them. Note that if there have been any changes in the values labels for specific variables, such as geographic areas or education categories or sources of water, the labels for the first survey will be over-written by the labels for the second survey. Variables that have changed their definitions will have to be recoded in one survey or the other.
