The country also has a slightly above-average enrolment rate in vocational education and training VET programmes in upper secondary education, with transitions possible from upper secondary VET programmes to tertiary education. Greater differentiations between VET and general upper secondary paths have taken place as part of broader reforms in 2011. The literacy and numeracy skills of Swedish adults (16-65 year-olds) are higher than in other countries participating in the Survey of Adult Skills, with younger adults (16-24 year-olds) scoring even higher in literacy and problem solving than other adults. Unemployment is lower than the OECD average. The economic crisis has had a large impact on those who did not reach upper secondary level.
