This trend may reflect in part the effects of technological change and globalisation, which have raised demand for highly educated workers and changed the nature of skills needed in the workplace (Riddell, 2001). Canada currently leads the OECD with the highest proportion of adults aged 25-64 that have completed tertiary education at 49%, compared to 30% for the OECD average (OECD, 2011a). This share rises to 56% for the cohort of 25-34 year-olds, exceeded only by Korea. However, this ranking reflects a remarkably high community college attainment rate; at 24%, Canada boasts the highest share of adults with a college (tertiary-type 5B) education, versus the OECD average of 10% (Figure 2.2, Panel A).
