The contribution of these factors has been different for the OECD economies and non-OECD countries during the last 25 years. Populations in OECD countries are getting older due to slowing population growth and increased lifespans. Such demographic prospects will have considerable effects on the size of the labour force, and hence, potential employment and output growth. Accordingly, under the low- growth scenario, structural unemployment in OECD countries is expected to remain at current high levels in Europe, while being stable elsewhere. Structural unemployment would also fall significantly in the non-OECD economies with large informal sectors.
Turkey offers a sound demographic outlook.
Indeed, Turkey has a much greater land area than any other European Member of the OECD and already ranks second in terms of population in this group, after Germany. Turkey will have the largest population in the year 2020. This will mainly be due to the fact that while population growth rates are expected to fall in most OECD countries, Turkey will continue to experience population growth up until 2020 and even beyond, though the rate of growth will continue to slacken significantly by the coming decades. Turkey's population is expected to be 83 million in 2020. As a result, Turkey will not have to cope with the problems that most OECD countries will be facing due to ageing populations.
