The incidence of NSW is 40% among younger workers (versus 30% for prime-age), and it is over 50% in Australia, the Netherlands, southern Europe and Poland. This mostly involves younger workers on temporary contracts. On average in the OECD, 43% of temporary workers are aged 15 to 29, and this share is over 60% in Austria, Germany and Switzerland, suggesting that these jobs are often entry ports for young workers (figures not shown). The incidence of non-standard employment is highest among workers with a lower level of education (around 44%) and lowest among the higher educated (Figure 4.4).
