Following is response from DHS Research & Data Analysis Director, Tom Pullum:
On page xxiii of the report you will find this paragraph: "The 2008 EDHS also collected information on a number of other health topics from 6,578 women and 5,430 men age 15-59 living in a subsample of one in four of the households sur[1]veyed. Among the key topics covered in these interviews were knowledge and awareness of avian influenza, HIV/AIDS and hepatitis C; pre[1]vious history of hypertension, cardiovascular illness diabetes and liver disease; attitudes and behavior with respect to female circumcision; health care costs; and health insurance coverage."
I did the merge with the lines given below. I reduced the respondents in the OD file to ever-married women age 15-49. Then, out of the 16,527 women in the IR file, I was able to find 4,181, almost exactly one in four, in the OD file. This is consistent with one fourth of the households being selected for the OD survey.
You merged with about 17% of women, rather than 25%, because you retained men, women age 50-59, and never-married women in the OD file. However, your merge was ok.
When users find a result like this, I recommend checking for subsampling on some of the key variables. Just go to the pdf of the final report and search for the word "subsample" and you will probably find the explanation.
