Migration & diaspora
Why people move; how ideas travel with them.
What is migration?
Migration means moving from one place to live in another. People migrate within countries or across borders. Sometimes they move for a few years; sometimes forever. Migration has shaped human history for thousands of years. Today, around one in thirty people worldwide lives outside their birth country.
Push and pull factors
Push factors drive people away from home: war, famine, natural disasters, or lack of jobs. Pull factors attract people to new places: safety, work opportunities, better schools, or family already living there. Most migrants weigh both push and pull factors before deciding to move.
Types of migration
Voluntary migration happens when people choose to move for better opportunities. Forced migration occurs when people must flee danger or persecution. Internal migration means moving within the same country, like from village to city. International migration crosses national borders. Refugees are people forced to leave due to conflict or persecution.
Diaspora: Communities across borders
A diaspora is a scattered population originally from one homeland. The Irish diaspora spread worldwide during the 1800s famine. The African diaspora resulted from the slave trade and later voluntary migration. Diaspora communities keep cultural traditions alive while adapting to new homes. They often maintain language, food, religion, and festivals from their ancestral land.
How migration spreads ideas and culture
Migrants carry their culture, skills, and knowledge with them. This enriches their new communities. Food, music, technology, and beliefs travel along migration routes. For example, curry became popular in Britain through South Asian migration. Chinese communities brought acupuncture and martial arts worldwide. Migration makes societies more diverse and innovative.
Worked examples
1. The Singh family left Punjab in 1960 because of drought and lack of farmland. They moved to Birmingham where Mr Singh's brother had a factory job. Identify one push factor and one pull factor.
- Push factors make people want to leave: drought and lack of farmland made farming impossible.
- Pull factors attract people to new places: Mr Singh's brother had a job and could help them settle.
- Answer: Push = drought/lack of farmland; Pull = job opportunity/family already there.
2. Polish communities in Chicago celebrate traditional harvest festivals and teach children Polish language on Saturdays. Explain how this shows diaspora culture.
- A diaspora maintains links to their ancestral homeland even while living elsewhere.
- The Chicago Poles keep cultural traditions (festivals) and language alive in their new country.
- This shows diaspora communities preserve their heritage while building new lives abroad.
3. After the 2004 Indian Ocean tsunami, thousands of Sri Lankans moved to safer inland areas. What type of migration is this?
- Check if the move was within one country or across borders: inland means within Sri Lanka.
- Check if people chose to move or were forced: a tsunami is a natural disaster forcing people away.
- Answer: This is forced internal migration (within the same country, due to disaster).
Try it yourself
Maria's family left Venezuela in 2018 because of food shortages and moved to Colombia where jobs were available. Identify whether this is voluntary or forced migration, and whether it is internal or international.
