Integration of sample design for the National Survey of Family Growth, Cycle IV, with the National Health Interview Survey.

Research was undertaken to develop alternative methods of selecting a sample of eligible women for the National Survey of Family Growth (NSFG) from the National Health Interview Survey (N HIS). This report presents estimates of the effects of alternative design options, obtained by statistical modeling techniques, for linking the NSFG with the NH IS. The estimated survey costs, lengths of data collection period, and projected response rates for alternative linked design options and for the unlinked design are compared for fixed precision. The findings indicate that substantial gains in the NSFG design efficiency could be realized if particular linked design options are adopted to replace the independent design.
