摘要：This paper presents a survey of results about studies on ageing. The data is collected from population projections by the United Nations, OECD, the European Union and the Eurostat.The research question is how population ageing affects the percentage of the working age population in the OECD. Special focus countries are the Nordic countries. The method is to collect together comparable data from these previous studies. The results imply that from 2005 to 2050 the number of the elderly in relation to the working-age population is projected to increase radically. Most advanced national economies are likely to have problems in providing elderly care services and pensions. In addition, post-industrialisation and ethnic discrimination add to the problem by excluding a fair share of the working-age population from the labour market.
