This chapter first sets out the most important elements of pension reform in the 34 OECD member countries between January 2009 and September 2013. It thus updates and continues the analysis in the 2009 edition of Pensions at a Glance which examined pension reforms from 2004 to the end of 2008. The second part of the chapter examines the distributional impact of pension reforms over the last 20 years, looking only at those countries which have undertaken reforms that go beyond solely raising the retirement age.
