Migration is a feature of social and economic life across many countries, but the profile of migrant populations varies considerably. In part this is because of the variety of sources of migration. In much of Europe, for example, citizens enjoy extensive rights to free movement. In Australia, Canada and New Zealand, managed labour migration plays an important role. Other sources include family and humanitarian migration. Whatever its source, migration has important impacts on our societies, and these can be controversial. The economic impact of migration is no exception. Benefit or burden – what’s the reality? To answer this question, it can be helpful to look at migration’s impact in three areas – the labour market, the public purse and economic growth.
