Intergenerational Studies (IGS)

The Intergenerational Studies (IGS) are one of the most comprehensive and longest running longitudinal studies of human development in the world. The IGS is composed of three studies initiated at the Institute for Human Development (IHD) in the late 1920s and early 1930s and have continued for more 75 years. The three studies composing the IGS are the Berkeley Growth Study (BGS), the Guidance Study (GS) and the Oakland Growth Study (OGS). Information regarding the three samples, measures used in the study, and family data collected can be found on this website. Additional information regarding the samples, measures, and timing of assessments can be found here.
