The aim of this article is to identify the main mechanisms leading to the NEET status in Italy, Romania, and Bulgaria. It does so by highlighting the differences amongst them and verifying how place of residence effectively affects the connected propensity to this status after having controlled for many personal characteristics through a series of probit models. Furthermore, multiple correspondence analyses produce profound understanding of the NEET phenomenon and associated determinants. The results highlight the need to plan support actions tailored to specific NEET characteristics. Whilst the degree of urbanization impacts upon the NEET status throughout Romania and Bulgaria, Italy shows a strong divide between the North and the South. However, in all three countries there is a need to improve the education system and stimulate higher levels of education as the main measure of NEET prevention.
