ABSTRACT
Immigration flows have continued or intensified in the last two decades in many West European countries, some of which have been attracting large numbers of immigrants since the 1950s and 1960s. Countries that were previously net senders of emigrants - such as Ireland, Italy, Portugal and Spain - have become, since the 1980s and 1990s, net receivers. Together with Ireland, nowhere has this reversal of population flows changed so dramatically and rapidly as in Spain (see Chapter 3 in this volume).
