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.

Data collection for the Infant Cohort started in 2008 with over 11,000 9-month-olds and their families.  Follow-up waves were completed when the child was aged 3 years, 5 years, 7/8 years (postal), 9 years and 13 years old.  Depending on the particular wave, information has been collected from parents, carers, non-resident parents, teachers and principals.
