Migration in London
London has also been greatly affected by migration. Within the last 20 years, more UK residents moved out of London than moved into London. However, the large number of financial and knowledge-based job opportunities has attracted people from the rest of the world. Within the same time period, more international migrants have moved into London than have moved out. The overall effect is that in recent years, more migrants have been moving away from the city than have moved into it.
It is estimated that up to a third of all international migration into the UK is into London. As a result, London has the most culturally-diverse population in the UK. Many of the people that come to London as international migrants then leave the city to live elsewhere in the UK. Young adults in their 20s and 30s typically move to the city and then move out again as they age and have families. This gives London a different population structure to the rest of the UK, as it has many more younger people of working age and fewer children.
