Answer:
Initially, internal migrations in many countries (Russia, USA, Canada) were associated with the colonization of vacant or sparsely populated countries. With their exhaustion, such migrations have lost their former scope and significance. However, in a large number of developing countries (China, Indonesia), the role of migration within the district, which is associated with the development of huge, hitherto sparsely populated territories, is still large. In the 1950s, more than 5 million people were relocated to another island from densely populated Java.
