Migration waves are patterns in population movement where large numbers relocate in a relatively short period, creating noticeable shifts in the demographic makeup of origin and destination areas. Waves are characterized by temporal clustering and often by rapid surges linked to broader macroeconomic or political changes.

They arise from push factors in origin regions (unemployment, conflict, climate stress) and pull factors in destination regions (labor demand, safety, higher living standards). Social networks, information flows, and transport improvements lower migration costs and enable chain migration, which sustains or accelerates a wave.

Waves typically unfold in phases: initiation, rapid expansion as more migrants join, a plateau as destinations adjust, and either stabilization or a new wave triggered by renewed conditions. Policy regimes, border controls, and asylum rules can influence the size and duration of waves.

Historical examples include the Great Migration in the United States (early 20th century) and postwar European labor migrations (1950s–1970s). Contemporary waves have been shaped by wars, displacement, and climate-related events, producing large flows into Europe, North America, and other regions.

Impact assessments examine demographic changes, labor markets, urban development, cultural exchange, and social cohesion. Data from censuses, surveys, and border records support analysis of causes, pathways, and consequences to inform policymaking and planning.
