The fifth in a series of reports presenting analyses and discussions of data on height, weight, and 28 other body measurements taken from a probability sample of noninstitutionalized children in the United States aged 6-11 years, this document compares the growth patterns of white and Negro children for 20 body measurements. Emphasis is placed on comparisons of age and sex specific means and medians for Negro and white children. These national estimates are based on cross-sectional data, which are said to limit the analyses to attained size rather than velocities of growth. All dimensions are said to increase almost linearly with age from 6 through 11 years in Negro and white children, both males and females. Conclusions derived from these data are considered to agree generally with most other anthropometic comparisons of American white and Negro children with these statistics providing figures held to be current, comprehensive, and reliable national estimates. Twenty-six detailed tables of statistical material are provided. (Author/AM)
