Many asylum seekers flee their own country because there is a civil war there or because their human rights are not being respected.
The top five countries that people came to the UK from in 2007 were:
- Afghanistan (2,500)
- Iran (2,210)
- China (2,100)
- Iraq (1,825)
- Eritrea (1,810)
In some countries, people can be arrested, sent to prison or even tortured for their religious or political beliefs.
If the situation in a country changes for the better then there are often fewer asylum seekers from there.
