HYBRID OPTION

The hybrid option combines features of the 2000 census frame option and the 1990 census frame option. Part of the sample would be selected using the 2000 census frame option and the remainder using the 1990 census frame option. Under this option, the 2000 census would be used to draw a sample of college graduates of (nominally) about half the size of that planned under the 2000 census frame option. The subpopulations consisting of foreign-trained college graduates and those with non-S&E degrees who have moved into S&E occupations since April 1993 would be represented by this part of the total sample. The remaining portion of the sample would be derived from the existing SESTAT panel, which would be subsampled, bringing its size to (nominally) about half of the total current sample size (Westat, 2002a).
