Comparability
Changes in the universe between samples limit the comparability of this variable. From 1994 to 1996, sample children who are older than 2 years old but younger than 6 years old and all children aged 19-35 months who were not selected as sample children were asked of this question. In 1991-1993, only sample children who are older than 2 years old but younger than 6 years old were included.
Users can exclude all children aged 19-35 months in 1994 to 1996 who were not selected as sample children, using IMMSAMP
