"Education Indicators in Focus" is a recurring series of briefs that highlight specific indicators in "OECD's Education at a Glance" that are of particular interest to policy makers and practitioners. They provide a detailed look into current issues in pre-primary, primary and secondary education, higher education, and adult outcomes from a global perspective, and contain an engaging mix of text, tables and charts that describe the international context of the most pressing questions in education policy and practice. This brief reports that on average across 15 OECD (Organisation for Economic Cooperation and Development) countries, a 30-year-old male tertiary graduate can expect to live another 51 years, while a 30 year-old man who has not completed upper secondary education can expect to live an additional 43 years. A similar comparison between women in the two educational groups reveals less of a difference than that among men. In 27 OECD countries, on average, 80% of young tertiary graduates say they vote, while only 54% of young adults who have not completed upper secondary education do so. The difference in voting rates by level of education is much smaller among older age groups. Education can bring significant benefits to society, not only through higher employment opportunities and income but also via enhanced skills, improved social status and access to networks. By fully recognising the power of education, policy makers could better address diverse societal challenges.
