What is the term for migration that takes place within a country?

The term for migration that takes place within a country is referred to as domestic migration. This type of migration encompasses the movement of people from one location to another within the same nation, such as moving from one city to another or from rural areas to urban centers. Domestic migration can have significant implications for population distribution, economic development, and regional dynamics within a country.

In the context of migration terminology, international migration involves crossing national borders, which is not applicable here since the question specifies movement within a single country. External migration typically refers to leaving one's home country for another. Rural-urban migration is a specific form of domestic migration where individuals move from countryside areas to cities, but it does not encompass all types of domestic movement. Therefore, domestic migration is the most accurate and comprehensive term for migration occurring within a nation's borders.
