The data below illustrates the statistics about temporary migrant workers in four countries in 2003 and 2006, and the contribution of these workers per 1000 people in 2006.
Overall, the increase in the number of temporary migrant workers in New Zealand is the least in comparison to the other three countries, but the contribution per 1000 people in 2006 is the highest for this country. Also, the numbers for the UK have almost doubled over three years, but the contribution is the least for them.
On the one hand, the US received about 100,000 temporary workers from abroad, but the proportion per 1000 people made up only 2.3, making it the lowest among these four countries. Similarly, the UK let into the country more than 130,000 migrant workers in 2006, making the number two times more than in 2003, while the portion of them per 1000 people comprised only 4.4.
By contrast, the number of temporary working migrants for New Zealand increased by only 23,000; nevertheless, the proportion of them made up 21.1, which is the highest. Moreover, Australia has almost two times less proportion of migrant workers per 1000 people than New Zealand, but the increasing trend shows 1.5 times more quantity in the three-year period.
