Summary "This investigation of the relation between the order of birth and the intelligence of children as well as a number of related questions has been carried out on data collected at the Institute for Juvenile Research. A large part of the work was carried out under the auspices of the Behavior Research Fund, and it was completed by some work under the auspices of the Local Community Research Committee of the University of Chicago. The first part is an analysis of our own data, and the second part, for which Dr. Jenkins is chiefly responsible, is a summary of the literature on this and closely related problems. The first part of this study is the work of both authors. The conclusions of this investigation, which indicate a steadily increasing advantage in intelligence in favor of the later-born children, are based upon the Institute population of children. These children come to the Institute usually for some behavior problem, and their mean intelligence quotient is in the vicinity of .80. Although the mean intelligence of our population is lower than the average for the general population, we have seen no very good reason to suspect that this fact would in any way influence our main problem. We have been interested in the relative intelligence of the first-born, the second-born, and the third-born child in each family rather than in the mean intelligence of the whole population.
