What The Mail (surprisingly) doesn't reveal is that immigration figures have been fairly consistent over the past decade but emigration has declined to skew the figures. Nor does it mention the benefits of immigration. The following go some way to address the journalistic bias which is so out of character for that newspaper.
OECD report 2011:
Migrants contribute to the economic growth of their host countries in many ways, bringing new skills and competencies with them and helping to reduce labour shortages. An aspect that has received only limited attention up to now is migrants' contribution to entrepreneurial activity and employment creation in their host countries. In OECD countries, entrepreneurship is slightly higher among immigrants than natives and the total number of persons employed in migrant businesses is substantial, although the survival rate of these businesses is often lower than that of their native counterparts. Migrant entrepreneurship has gone beyond traditional ethnic businesses, into a wide range of sectors and innovative areas.
Office of National Statistics 2011:
This increase in net migration is driven by a fall in emigration, which was 344,000 in the year to September 2010, a decrease of 20 per cent from its peak of 427,000 in the year ending December 2008. Over the same time period, immigration has remained steady at 586,000 in the year to September 2010, which is similar to 590,000 in the year ending December 2008.
