The sample for this study of the U.S. population was selected from households in 81 counties across the United States. About 40,000 persons 2 months of age and over were selected, including large samples of both young and old persons. About 12,000 of the sample persons were black Americans, 12,000 were Mexican-Americans, and the remaining 16,000 were of all other race and ethnicity groups. All selected persons were asked to complete an extensive interview and an examination in a large mobile examination center. The survey period is 1988-94, consisting of two phases of equal length and sample size. Both Phase 1 and Phase 2 were random samples of the U.S. population living in households.
