Tusla commissioned this research study in order to establish how Ireland compares to other jurisdictions, in relation to the collection and publication of data on child protection and welfare services. Its focus has been on what data is collected in other jurisdictions, how it is collated and whether it is comparable. As well as generating substantive data for comparison, the study has involved attention to information on definitions, procedures and legislation/policy. It has also required engaging with extant knowledge on comparing child protection and welfare systems and on comparing data about these systems. It is primarily a desk based study, but has involved some contact with national experts in the field.
