The pie charts illustrate some factors that lead to migration to and from the the UK in 2007. Overall, work-related purposes are the most common reasons for this phenomenon, while formal study also influences a large number of foreigners to come to the UK.
The most influential factor is a definite job, which is the reason for 30% of immigrants and 29% of emigrants in the UK. In the emigration pie, the purpose of looking for a job comes in second place with 22 percent, and only 4 percent is for formal study, which is the least effective reason to emigrate. Meanwhile, it is completely different on the immigrant side, with 26% of foreigners going to the UK due to study purposes, making it the second-largest proportion. Looking for a job is also common, but it is not as high as it is in the emigration pie, at 12%.
The amount of people who migrate because of accompanying or joining is approximately the same, at 15% and 13% for emigration and immigration, respectively. Besides, 18% of people moving from the UK do not give out the reason, more than twice the percentage of migration to the UK, which is only 6%. Lastly, other factors accounted for 14% of the emigration, more than 3% of the immigrants.
