Economic struggles across the world's top economies has would-be migrant workers staying home.

A report released Tuesday by the Paris-based Organization for Economic Cooperation and Development found overall migration into its 34 member states fell by seven percent in 2009. Migration by temporary workers fell even more, dropping 17 percent.

The OECD report said most marked declines in migration came in Asia and Europe, while fewer illegal immigrants from Latin America tried to enter the United States.

More recent data suggests those trends continued last year, but OECD Secretary General Angel Gurria said demand for migrant workers is expected to rebound.

Gurria said globalization and aging populations in member countries will spark a greater demand for migrant workers. He said governments will need to find better ways to attract legal migrants and make use of their skills.

The OECD report also found half of all international migration now takes place among developing countries, with China and India among the top sources of migrants to OECD countries.

The recent Arab unrest has also affected migration, leading to an increase in the flow of people to Italy, France and even Africa.

The thousands of mainly North African immigrants who have flocked to Europe in recent months have prompted calls for tightening European borders. European Home Affairs Commissioner Cecilia Malstrom says the bloc has offered help to some.
