Global migration impacts national politics by shaping demographics, influencing labor markets, and altering public policy. Migrants contribute to economic growth while also posing challenges in terms of integration and social cohesion. Countries may modify their immigration laws and welfare policies in response to shifting populations. Furthermore, rising migration can lead to political polarization, as debates over immigration often evoke strong sentiments. Addressing these impacts requires constructive dialogue and policies that acknowledge the benefits and challenges migrants present, fostering a more inclusive political environment.
