Growing Up in Ireland (GUI) Cohort ’08 (Infant Cohort) Wave 2 - 3 years, 2011

Growing Up in Ireland - the National Longitudinal Study of Children, is the first survey of its kind ever undertaken in Ireland and, as such, aims to explore the many and varied factors that contribute to or undermine the wellbeing of children currently living there. A two age cohort longitudinal design was adopted with one cohort of 11,134 infants (aged nine months) and the other of 8,568 nine-year olds, with a view to improving and understanding of children’s development across a range of domains. Since the survey is longitudinal in nature respondents in both cohorts are interviewed on a number of occasions over the folowing few years. The 11,134 children representing the infant cohort were born between 1st December 2007 and the 30th June 2008 and data collection for the first wave at age 9 months took place between September 2008 and April 2009. Data collection for the second wave at age 3 years took place between December 2010 and July 2011 and resulted in a completed datafile of 9,793 cases.
