Data on the intellectual maturity of children 6-11 years of age in the noninstitutionalized population of the U. S. is analyzed in relation to their demographic and socioeconomic background. This is the second report on the Goodenough-Harris Drawing Test, administered in the Health Examination Survey of 1963-65, and deals with the results in relation to factors of race, region, size of place of residence, grade in school, education of parent, and family income. For this survey, a probability sample of 7,417 children was selected to represent the 24 million noninstitutionalized children in the U.S. While white children scored higher than Negro children on this test, the racial differential is lower than on the Wechsler Intelligence Scale for Children and the Wide Range Achievement Test, and is reduced to a negligible amount when the effects of differences in parent's education and family income are controlled. The performance of children on this test does not differ appreciably among the four regions of the Nation, except in the South, where children of both races fall below those in other regions. Size of place of residence is not consistently related to test scores. There is a slight but consistent association between drawing test scores of white and Negro children and rate of population change in the 1950's. Children over the modal age for school grade do more poorly than those below, while those at the modal age yield consistently average scores. Father's education and family income both show a relationship to children's scores. Included are descriptions of the drawing test, the survey design, and reliability estimates. Comparisons are made with previous research using this type of instrument. (Author/DB)
