1.There are significant differences between EU Member States with respect to national definitions and recording practices, for instance with regard to the age limit to be considered and whether or not they are unaccompanied.
2. In some (EU Member) States, statistics include all those who claim they are unaccompanied minors (i.e. before an age assessment has confirmed this), whereas other (Member) States only count those recognised as such by a competent authority (i.e. following an age assessment).
3. For further information, see EMN: Policies on Reception, Return and Integration Arrangements for, and numbers of, Unaccompanied Minors – an EU comparative study, 2009. An update of this 2009 study was published in 2015 entitled ‘Policies, practices and data on unaccompanied minors in EU Member States and Norway'.
