Germany stands out among the countries where immigration increased in 2012 according to the Organisation for Economic Co-Operation and Development (OECD; pdf) .
Flows increased by over a third compared with 2011, reaching 400 000 persons. Germany became the second-largest immigration country, after the United States, in the OECD in 2012, receiving more than 10% of all permanent immigration to the OECD area. In 2009, it was only the eighth largest. This spectacular increase has been fuelled mainly by inflows from central and eastern European countries and, to a lesser degree, southern Europe.
Looking at the evolution by country of destination gives an even more complex picture. Apart from Japan and Korea, where immigration remains at relatively low and stable levels, flows to other countries showed large variations over the first decade of the millennium. Spain displayed the widest variations, with inflows tripling between 2000 and 2007 before subsequently decreasing to a third of the 2007 peak. Trends observed in 2012 clearly illustrate this responsiveness to economic conditions.
According to most recent population censuses, between 2000/01 and 2010/11, the number of immigrants in the OECD increased by around 35%. In 2010/11 there were more than 100m foreign-born in the OECD compared to just over 75m a decade earlier.
A little more than half of the foreign-born, or 52%, were women and 75% were aged between 25 and 64. Mexico is the main country of origin with 11m emigrants, followed by China (3.8m), the United Kingdom (3.5m) and India (3.4m). The number of immigrants in OECD countries who were born in China, India and Romania has increased by more than 1.5m in ten years.
Overall, international migration flows to OECD countries are a third higher in 2010 than they were in 2000. At first glance these facts may support the idea of a constant, if not accelerating, increase in migration.
