Description

Birth weight, date, and gestational period collected as part of the Child Health and Development Studies in 1961 and 1962. Information about the baby's parents — age, education, height, weight, and whether the mother smoked is also recorded. The data were present by Nolan and Speed to address the question of whether there is a link between maternal smoking and the baby's health.
