In 2015 it reached 50.2% (up from 45% in 2010), which is only slightly below the EU28 (the European Union’s 28 member states) as well as the OECD average of 53%. It is also higher than that of neighbouring countries as well as some of the Central and Eastern Europeans: 44% in Poland, 41% in Slovak Republic, and 43% in Russia and Ukraine (World Bank, 2016). The latter, referred to as the old age dependency ratio, has remained between 10 and 11% since 1960. Over the same period, the old age dependency ratio has increased from 14 to 25% across the OECD countries (World Bank, 2016).
