As many as 10 attempts were made to contact every sampled telephone number.
Sample was released for interviewing in replicates, which are representative subsamples of the larger sample.
Weighting was accomplished using Sample Balancing, a special iterative sample weighting program that simultaneously balances the distributions of all variables using a statistical technique called the Deming Algorithm.
Weights were trimmed to prevent individual interviews from having too much influence on the final results.
