This report on the Child and Youth Mortality in Ireland is the thirteenth report in the Statistical Spotlights series. These Spotlight publications are focused on a specific topic, and gather available statistical data to highlight trends or patterns. This Spotlight #13 collates available data from the CSO, Eurostat and Tusla on mortality among various subgroups of the population aged under 25 and across time, and also provides an international comparison. The spotlight report shines a light on how children and young people’s mortality has improved in the past 5 decades and collates information on more recent trends for this group, including how Ireland compares to the other EU27 countries and how mortality compares with children in care and young people availing of aftercare services to the general population in Ireland.
