The proportion of 15-year-olds engaging in intense physical activity is comparatively high (almost 59%, versus an OECD average of 52.3%), but overweight and obesity rates are also relatively high - almost 28% of 11-15 year-olds in Canada are overweight or obese, compared to an OECD average of 19%. Not all children benefit from optimal conditions for studying: about 18% of 15-year-olds in Canada do not have a desk and quiet place to study at home, 26% do not have books to help with school w'ork, and 36% feel anxious about school tests even if w'ell-prepared. Nevertheless, Canadian teenagers perform very well on the OECD’s PISA reading and mathematics tests, and the proportion of 15-year-olds who plan to pursue higher education is comparatively high. The adolescent (15-19 year old) fertility rate is also near the average for OECD countries.
