„PISA 2022 shows that the occupational expectations of students are highly concentrated. Looking at the ten most popular job plans shows that on average across the OECD 50% of girls and 44% of boys expect to work in one of ten jobs. […] Since 2000, levels of this career concentration – which in some studies is associated with poorer ultimate employment outcomes later on – have steadily increased.“
