SN: 0020-05 - Growing up In Ireland Cohort ’98 (Child Cohort) Wave 5 - 25 years, 2023

About the Study

Growing Up in Ireland - the National Longitudinal Study of Children is a landmark study of children and youth which has been running since 2006.  The objectives of the study are outlined in a separate publication (Greene et al. 2010).  In summary the project seeks to further our understanding of what it means to be a child or young person growing up in modern Ireland, with a view to informing policy on what both helps and hinders development. A two cohort, cross-sequential longitudinal design was adopted and began with one cohort (Cohort 08) of 11,134 infants (aged 9 months) and a second cohort (Cohort 98) of 8,568 9-year-olds. A third cohort (Cohort 24) will follow infants from age 9 months. Being longitudinal in nature, the same children are followed over time. The families of Cohort 08 have been interviewed when the children were 9 months, 3 years, 5 years, 7/8 years, 9 years and subsequently at 13 years of age, while Cohort 98 and their parents/guardians were interviewed at 9, 13, 17/18 and 20 years of age. This dataset relates to Wave 5 of Cohort 98 when respondents were 25 years old.
