Abstract:
|
The National Health Interview Survey (NHIS) is a continuous survey that collects health data using personal interviews. Changes have been made in the sample design for the NHIS (a "redesign") about every 10 years, using information from the previous decennial census. The 2006 NHIS is the first year of the most recent sample redesign. Beginning with the previous design---implemented in 1995---and continuing with the 2006 design, minority persons are oversampled using two mechanisms: variation in sampling rates in substrata and screening. Primary sampling units are partitioned into substrata based on population proportions of minority persons, and substrata with higher minority population proportions are sampled at a higher rate. A proportion of the sample cases are "screened" (i.e., the household interview stops if no eligible minority persons are on the household roster).
