Final answer:
The UK is ethnically diverse with around 200 ethnic groups, including large South Asian and African communities, as well as growing East European populations, contributing to its multicultural society.
Step-by-step explanation:
The United Kingdom (UK) is home to a rich tapestry of ethnic diversity due to immigration, historical colonial relationships, and international influences. With approximately 200 ethnic groups, this diversity shapes the UK's social, cultural, and political landscape. Among the largest minority groups are people of South Asian origin, including individuals with Indian, Pakistani, and Bangladeshi heritage, contributing to the multicultural fabric of cities like London.
There has also been a significant rise in African communities, primarily from former British colonies, as well as a growing number of East European residents following EU expansion. The UK's ethnic landscape continues to evolve, influenced by immigration patterns and the broader processes of globalization.
