Emigration is the act of leaving one country to live in another. It is the opposite of immigration. People emigrate for many reasons, including work, safety, or family connections.

Governments track emigration using records and statistics about population changes. Some people move temporarily, while others relocate for long periods. Emigration can involve individuals, families, or larger groups.

Emigration is studied in geography and sociology. It helps explain how populations change and move across countries.
