Growing Up in Ireland

Growing Up in Ireland is the national longitudinal study of children and young people, a joint project of the Department of Children, Disability and Equality (DCDE) and the Central Statistics Office (CSO). Since 2006, the study has provided Government with an evidence base to make informed policy decisions on a wide range of issues based on data from children and young people living in Ireland.

For over 17 years, the study has followed the progress of two groups of children: starting with over 8,000 9-year-olds (Cohort ’98) and 10,000 9-month-olds (Cohort ’08). The members of Cohort ’98 were aged 25 at their last wave of data collection (currently 26 years old), and those of Cohort ’08 will be aged 17/18 in their next wavwe of data collection (currently 16 years old). Recruitment of a new group of 9-month-olds, Cohort ’24, started in September 2024.
