CCC2000 comprises all children born in 2000 by women residing in one of 16 municipalities in the former Copenhagen County, Denmark. The cohort covers nearly 10% of all children born in Denmark in that year, while the catchment area consists of urban and semirural suburbs surrounding Copenhagen, with a mixture of high-, moderate-, and low-income households. All eligible cohort children and their parents were contacted and asked to participate in questionnaires, interviews, and assessments at key ages of development: 0-10 months and 1.5, 5-7, 11-12, and 16-17 years. In parallel, data from the Danish national registries have been drawn regularly.
