It impacts age distribution, sex ratio, and ethnic diversity within a population. Migration often occurs due to economic opportunities, affecting population growth or decline. Additionally, it introduces new cultures and traditions to a region, shaping its cultural diversity. Overall, migration plays a crucial role in determining the size, structure, and cultural dynamics of a population.
