How migration has changed over the last 100 years?

Over the last century, migration has evolved significantly due to globalization, technological advancements, and shifts in political and economic conditions. In the early 20th century, migration was often driven by labor demands and the search for better opportunities, with many moving from rural areas to urban centers or across borders. Today, factors such as climate change, conflict, and education play crucial roles in migration patterns, with increased movement of refugees and skilled workers. Additionally, modern transportation and communication technologies have made migration more accessible and interconnected than ever before.
