Weights were created to ensure proper representation of the U.S. population. The study team created base weights that considered the original probabilities of selection. The study team also adjusted for non-resolution and non-response at the screening and interview stages. Finally, the study team implemented raking adjustments to control-totals from the Current Population Survey based on age, gender, race-ethnicity, educational attainment, and Census division (region). After the weights were calculated they were combined by assigning a factor to each sample type based on the total number of interviews contributed by each source. The study team then implemented an additional round of raking adjustments using the same control totals as in previous steps. In data analysis, the unweighted data were used for the cluster analytical work that generated the typology. The weighted data were used to describe group differences on the demographic, political and health status measures and for all other data analysis work including the preparation of sample-wide frequency distributions.
