In this study we develop population projections for the non EU/non EFTA countries in Europe. The natural population dynamics recently observed in these countries are moving in a similar direction as in the rest of Europe, even though there is significant, country-specific heterogeneity regarding the intensity and timing of these changes. Contrary to other European countries, the majority of these countries will see a favourable period in terms of the characteristics of their population age profiles in the near future. With a low share of young and elderly populations on the one hand, and a prominent working-age population on the other hand, this demographic window could trigger socio-economic development. Yet this situation will only prevail during a short period, until the dependency ratio once more increases as the ageing process advances, which also seems to be an item on the future demographic agenda of these countries
