Migration to the world's most industrialized countries rose in 2005 with about four million new immigrants entering the OECD zone during the year, the organization said in a report last week.
According to the OECD's International Migration Outlook for 2007 the influx of immigrants, on a permanent basis, represented a 10% increase over the previous year.
"As with many other aspects of this agenda, the international mobility of people needs to be well managed, and sound policies designed and implemented," OECD Secretary-General Angel Gurria said.
"Migration is part of the solution for labor shortages and population ageing in OECD countries, but to take full advantage of it, effective integration policies are needed, in particular in the realms of education and the labor market." He said the inflows were highest in the U.S., Spain, Britain and Canada, but increased the most compared with 2004 in Ireland, South Korea and New Zealand.
