The global recession has dampened the movement of economic migrants to the major immigrant-receiving regions of the world.
But despite the increasing risk of unemployment, immigrants are choosing to stay in their adopted countries rather than return home, a report by the Migration Policy Institute for the BBC has found.
The number of international migrants was at an all-time high in 2005, with UN estimates at 195 million - 2.5 times more than in 1960. But there has been no single trend in how the recession has affected migration flows.
In Spain, the growth which attracted migrants in large numbers in recent years has come to a halt. As in the UK, Eastern Europeans with the right of return (and some Moroccans who have legal permanent residence) appear to be going home. But the Migration Policy Institute report suggests Sub-Saharan African and Latin American migrants seem to be staying put, mainly because of the poor situation back home.
The UK has seen a similar drop in the number of applications to the Worker Registration Scheme from Eastern European workers, as their home economies have strengthened. Data shows migrants from countries such as Poland tend to be temporary and circular -sometimes on a seasonal basis.
While data from the Gulf governments are hard to come by, the anecdotal evidence indicates that there have not been large-scale returns to India.
The majority of Indian migrants is comprised primarily of unskilled or low-skilled workers leaving for jobs in the oil-rich Gulf region.
To sustain the high levels of overseas employment of its nationals in the face of the recession, the Philippine government has embraced "full-blast market development efforts" that are likely to promote sustained emigration and limit returns.
Laid-off migrants who return to the Philippines are eligible for 10,000-peso (US$210) grants to obtain training in opening a small business.
Rising migration had led to increasing amounts of money being sent home by migrants. The financial crisis has meant that although these remittances have fallen, they have become increasingly important to immigrant-sending countries as other financial streams - such as lending or foreign investment - have fallen even more sharply.
Some regions are experiencing remittance increases or are holding steady. Remittances to Asia are rising as those to Latin America and Europe drop off.
