"Almost all Western European countries are experiencing an increasing inflow of immigrants. The statistics released by the OECD for the period 1994—2001 show that the ratio of immigrants (no matter how defined) has grown steadily in all Western European countries considered, except Belgium. These immigration flows are changing the societies of receiving countries in several respects. At the same time, however, the countries of Western Europe are also experiencing other important demographic changes, as they all are ageing population societies. A key issue, therefore, is how the combined effect of these demographic changes affects labor market outcomes."
