Following is a response from DHS Research & Data Analysis Director, Tom Pullum (Fred Arnold contributed to this response):
The NFHS-5 had a 15% subsample for men and for some topics in the survey of women. To achieve a representative 15% subsample, men were interviewed in alternate households in 30 percent of the randomly selected clusters. That's the reason why there were about 30,000 clusters in the entire survey, and that many distinct values of hv001 in the HR and PR files and v001 in the IR, KR, and BR files, but only about 9,000 distinct values of mv001 in the MR file. There should be no problem with svyset and svy, or with merges. This design is unusual but it makes sense as a strategy to get a 15% subsample in such a large survey.
