I have two data sets A and B. I have a variable in B that I can't observe in A however each data set contains common demographics from which I can create a interaction term in each data set (ie age,race,income,state) I can assign unique values to each interaction and merge the two data sets on this interaction therefore getting my varible of interest in set A. My question is that I can't get the number of observations in my merged data set to equal the number of observations in the master data set "A"(ie merge 3 contains more obervations than merge 1)Would the -joinby- command do what you want? If not, perhaps you could give us brief excerpts from the data along with the command(s) you are using.

I have tried the merge many times in addition to using every possible merge command out there, any response would be appreciated
