AN ALTERNATIVE SAMPLING STRATEGY FOR OBTAINING CHILD HEALTH DATA IN AREPRODUCTIVE HEALTH SURVEY

Retrospective demographic surveys typically collect substantial inform ation about child health. This information is often collected for all children born during a specified period. For women with several young children, the interview can become quite long. To shorten the intervie w, some surveys have asked child health questions only for the last ch ild born. However, data on the last birth may be biased because last c hildren have a younger age distribution and have longer subsequent bir th intervals than does the average child. In this paper, we propose an alternative approach to collecting child health data - that child hea lth questions be asked only for a child chosen randomly from among the respondent's children younger than age five. This alternative has the advantage of keeping the interview shorter but does not lead to biase d information.
