Growing up in Ireland Child Cohort Wave 3



Growing Up in Ireland is the national longitudinal study of children and youth in Ireland.  It started in 2006 and follows two cohorts of children aged 9 years (child cohort) and 9 months (infant cohort). It is the most significant survey of its kind ever to take place in this country, and will help us to improve our understanding of children and their development. The main aim of the study is to paint a full picture of children in Ireland and how they are developing in the current social, economic and cultural environment. This information will be used to assist in policy formation and in the provision of services which will ensure all children have the best possible start in life.

The Child Cohort started in 2008 with 8,500 children aged 9 years. Information was collected from parents, teachers, Principals and the children themselves. Additional perspectives were collected by post from non-resident parents and regular carers of the Study Child.  This cohort was revisited at age 13 years and most recently at age 17/18 years. This cohort will be visited again in the latter part of 2018 when they are 20 years old.
