Berkeley/Oakland longitudinal studies
type: Concept
broader: aging and older development
definition: The three longitudinal studies that constitute the Intergenerational Studies (IGS) of the Institute of Human Development (IHD) were initiated in the late 1920s, and the study members represent two birth cohorts: people born in Berkeley in 1928–1929 and people entering an Oakland middle school in 1932 (born in 1920–1921). Data were collected from and about them and their families through adolescence and, subsequently, from them and their spouses, parents, and children.
