The table illustrates the number of short-term migrant workers in four countries in 2003 and 2006 and that divided by 1000 people in these nations in 2006.
Overall, the USA seems to have the highest upward trend, which increased approximately 130000 people from 2003 to 2006.
The USA had the greatest number of migrating workers, which was more than half a million in both years, while New Zealand had the least number. Surprisingly, Australia had fewer migrant workers than the UK in 2003, but in 2006, the UK had a higher number than Australia.
The ratio between the number of temporary migrant workers in these 4 countries and the 1000 populations in their nations in 2006 was reverse to the number of employees. It can clearly be seen by New Zealand because they had only 87,000 temporary employees, but, on the other hand, had the strongest ratio (21.1 workers per 1000 people). As well as the United States, which is at the top but had the least number of these workers divided by 1000 US citizens.
To sum up, there was an increasing number of migrant employees from 2003 to 2006 in every country.
