I'm looking at IR files for ht/age standard deviations for the births that have happened in the last 5 years. I'm using variables hw5. However, unlike other rounds, I find that for DHS India 1998-1999, records are available in IR file for only the last 4 births in the last 5 years, instead of 6 births.

Were data collected on only the last 4 births in that round? All other rounds have information on 6 births.

Following is a response from DHS Research & Data Analysis Director, Tom Pullum:


This survey had a three-year window of time for the child health questions, including anthropometry, rather than the usual 5-year window. It will be much easier for you if you use the KR or BR files, in which children are units.

However, I see some differences.

/index.php?t=getfile&id=1891&private=0

Normally the children in the KR and BR files would be the same for the interval for the child health questions.

You say that you get up to 4 children. I only get 2 or 3, depending on which file I use. I don't understand where you found 4, but the main reason why there are fewer children than in most surveys is that the window was 3 years rather than 5.

You are using hw5, hw8, and hw11 for anthropometry. In the newer surveys, we use hw70, hw71, and hw72. There is a file "IAHW43FL.dta" that gives the newer (WHO) scores, and it can be merged with the KR or BR files. I strongly recommend using the newer scores for better continuity with recent surveys and more comparability with other countries. You should be able to find that HW (H for height and W for weight) file on the website. Let us know if you cannot find it.
