National Health and Nutrition Examination Survey (NHANES II), 1976-1980: 24 Hour Recall, Specific Food Item, Tape Number 5704

<p>The second National Health and Nutrition Examination Survey, NHANES II, is a nationwide probability sample of 27,801 persons from 6 months-74 years of age. From this sample, 25,286 people were interviewed and 20,322 people were examined, resulting in an overall response rate of 73 percent. Because children and persons classified as living at or below the poverty level were assumed to be at special risk of having nutritional problems, they were sampled at rates substantially higher than their proportions in the general population. Adjusted sampling weights were computed within 76 age-sex income groups in order to inflate the sample to closely reflect the target population at the midpoint of the survey.</p>
