Who are NEETs and how many are there in Italy?

The acronym NEET stands for Not Engaged in Education, Employment or Training and refers to young people (mainly between the ages of 15 and 34) who are neither engaged in education of any kind nor in vocational/work activities.
According to Eurostat, in 2021 there were more than three million young NEETs between the ages of 15 and 29 in Italy (Statistics on young people neither in employment nor in education or training – Statistics Explained.)
Well, what initiatives has the European Union promoted to be able to integrate them into education and employment?
