Hi DHS team,
I am using the Guatemala 2015 DHS dataset to analyze child stunting risk factors.
Using the Household (PR) file, I am able to replicate the stunting prevalence rates from the DHS report. However, I am wondering why I am getting such dramatically different numbers when I use the Children's file (KR)
My understanding is that the children in the KR file are a subset of children in the PR file. So it would make sense to have slight differences in the numbers between the two files.
Unweighted PR analysis: 6,607 stunted children out of 12,258 total children (53.9%)
Unweighted KR analysis: 8,170 stunted children out of 11,444 total children (71.4%)
But why would the percentages be so vastly different? Any why would there be MORE stunted children in the KR file if this is a subset of PR?
I have a feeling I am missing something obvious. Any help or guidance would be appreciated.

Dear User,
Here is a description of the two types od data files you reference:
Quote:
Household Listing Data - Household Member Recode (PR)
This dataset has one record for every household member. It includes variables like sex, age, education, orphanhood,
height and weight measurement, hemoglobin, etc. It also includes the characteristics of the households where the individual
lives or was visiting. The unit of analysis (case) in this file is the household member.
Quote:
Children's Data - Children's Recode (KR)
This dataset has one record for every child of interviewed women, born in the five years preceding the survey. It
contains the information related to the child's pregnancy and postnatal care and immunization and health. The data for the
mother of each of these children is included. This file is used to look at child health indicators such as immunization
coverage, vitamin A supplementation, and recent occurrences of diarrhea, fever, and cough for young children and treatment
of childhood diseases. The unit of analysis (case) in this file is the children of women born in the last 5 years (0-59 months).

Following is a response from DHS Research & Data Analysis Director, Tom Pullum:
Measurements of height and weight are taken during the household interview, for all children under 5 in the household and (usually) all women 15-49. That information goes into the PR file. Some households include children whose mother is not alive, or is alive but not living in the same household as the child. Then the eligible women are interviewed, and the data for the KR file is obtained. Height and weight are copied (during file construction) from the PR data to the KR data. The copying is limited to children who are living with their mothers.
Thus the calculation of stunting based on the PR file is representative of children in the household population, regardless of whether they are living with their mother. When based on the KR file, it is representative of children in the household population whose mother is alive and living in the same household as the child.
