AROUND 4m people moved to OECD countries in 2006, 5% more than the year before, according to the OECD's annual migration report. Joining family members and seeking employment were the main reasons, accounting for 44% and 14% of all arrivals respectively. America is by far the most popular destination, taking 1.3m migrants. China provides the biggest share of legal immigrants to OECD countries (though Britain and Ireland do not monitor nationality). Chinese migrants made up the biggest group in South Korea, Japan and Canada, and the second largest in America after Mexicans.
