The BCS is a longitudinal cohort study that started in 2002 with the aim to follow children born in Bergen, Norway in 1993 to 95 from early school age to college. During the first month of 2012, children born in Bergen between 1993 and 1995 were invited to participate. As of March 2024, the study consists of four data collection waves, and the first three of them, at ages 7-9, 11-13 and 14-16 years, were carried out in 2002/2003, 2006 and 2009. The final data collection wave was renamed "youth@hordaland", and was carried out in spring 2012, when the participants were 17-19 years of age.
