Good panel surveys that follow individuals over time and provide data on the longer term impact of evaluation and the dynamics of movement between different segments of the labour market are even rarer. Where LFSs exist, they are often outdated (more than five years old) and do not contain adequately disaggregated data (by age, gender, location). In the country expert survey only six respondents considered the government to have very good knowledge of the situation of youth in the labour market. The governments of 14 countries are considered to have only little or no knowledge. The lack of data makes it difficult for policy makers to understand the nature of the employment challenge and take informed decisions on how to support young people in the labour market.
