Following is a response from DHS Research & Data Analysis Director, Tom Pullum:
Stunting is based on the HAZ, the height-for-age Z score. I checked how many children have a HAZ score in the KR and PR files.
That is, there are 211,089 measured children in the KR file and 213,860 in the PR file. The N is smaller in the KR file than in the PR file, as you would expect. I don't see how you could have gotten the reverse.
Note that the KR file includes children who died, and children who are not living with the mother and for that reason there are children in the KR file who are not in the PR file. The Z scores--and stunting, etc.--are only obtained for children who are alive and in the household and whose height and weight were measured. There are more children with Z scores in the PR file than in the KR file because the height and weight measurements are part of the household survey and there are a few children in the household survey whose mother had died or is living elsewhere.
