The “Körmend Growth Study” (KGS), a chain of repeated cross-sectional growth studies performed every ten years on children in the town of Körmend (Hungary, Central Europe) was one of the first long-term research projects extensively tracing the secular trend. The data presented here is of 60 years, starting from 1958 to 2018 which is still continuing.

The data presented here are from the “Körmend Growth Study” (KGS). The KGS was set up by professor Eiben. Dr. Ottó Eiben (1931–2004), who was professor and chair at the Department of Anthropology at Eötvös Loránd University, and, after his retirement, a fellow at the Churchill College in Cambridge. He is considered the most influential figure in Hungarian human biology. The principal field of his scientific research activity was the growth and maturation of children and the secular trend. In this aspect, his most significant contributions were the Hungarian National Growth Study (Eiben et al. 1991)
