A total of 87 traditional and functional body measurements were taken on a sample of 4,127 infants, children and youths representing the United States population aged 2 weeks through 18 years. Measurements were taken throughout the United States by two teams of anthropometrists using an automated anthropometric data acquisition system. Standard anthropometers, calipers, and tape devices were modified to read electronically and input dimensional data directly to a mini-computer for data processing and storage. Summary statistics of measurement results are reported for 16 age groups along with scatter plots of the data points for the sexes combined and males and females separately. Each measurement is described alog with a photgraph and illustration. In addition, bivariate relationships of selected functional measurements with weight or stature are provided along with regression data.
