Patterns of migration between former colonies and the imperial core country have always been strong and has continued after independence
A key connection is often language and culture
Migration from Jamaica and India to the UK
Northwest Africa (Maghreb region) to France
These patterns are still evident and important in changing the ethnic composition and cultural heterogeneity within countries of destination
Britain and former colonies
After WWII, there was a general shortage of workers, and many people migrated from past colonies, to fill those gaps in employment
People from Jamaica (Windrush generation) travelled to the UK to work in transport and healthcare
Some migrants were directly recruited for their skills (London Underground recruited bus drivers from Kingston in Jamaica)
Britain and former colonies
The newly established National Health Service, lacked trained doctors after the war and many doctors travelled from India, Pakistan and parts of Africa to Britain
Medical schools in India used the same textbooks as British teaching hospitals allowing Indian doctors to fit in with the way medicine was conducted in the UK
Other people simply migrated, as was their legal right, as British citizens
All these movements have increased British cultural heterogeneity, particularly in London, Liverpool and Bristol
