Why migration rate was so high in the 1970?

The high migration rate in the 1970s was driven by various factors, including economic instability, political upheaval, and social changes in many regions. In the U.S., the post-Vietnam War era saw an influx of refugees, particularly from Southeast Asia, while economic challenges prompted many to seek better opportunities abroad. Additionally, decolonization and conflicts in Africa and Latin America contributed to increased migration as people fled violence and sought stability. Overall, a combination of push and pull factors led to significant population movements during this period.
