The process of migration likely varied between regions, but certainly involved the movement of human populations and cultural exchanges between populations.
The increase comes after migration to the UK in 2020 and 2021 was affected by the global Covid pandemic, when people were largely unable to travel as countries tried to tackle the spread of the virus.
