|
The National Survey of Family Growth (NSFG) is the primary source of information regarding fertility, family size, and healthy sexual practices for people between the ages of 15 and 44 in the U.S. The NSFG collects data from four national quarter-samples each year, and relies on responsive survey design strategies to minimize the errors and costs associated with its continuous sample design. Accordingly, the NSFG collects a large amount of paradata, including several different types of interviewer observations, and also purchases auxiliary data for the sampled addresses from commercial marketing organizations (e.g., MSG). These different types of auxiliary variables are used for many purposes, including over-sampling of likely eligible households, case prioritization during data collection, and adjustment of survey weights for nonresponse after data collection. This presentation will provide an overview of recently published studies considering the quality and utility of these different auxiliary data sources, given their roles in the NSFG. Suggestions for practice synthesizing results from the studies published to date will be provided in conclusion.
