South-South Migration Rising

International Migrants 1990-2024

Millions of people living outside country of birth

Key Finding: Migrants doubled from 154M (2000) to 304M (2024). Growth accelerated post-2010 (+4M/year) due to Syria crisis, Venezuela exodus, economic migration to Gulf states. Female migrants now 48% of total, up from 46% in 1990.

Top 10 Migration Corridors (2024)

Bilateral migrant stocks in millions

Key Finding: Mexico→USA (11.2M) largest corridor, driven by economic ties, family reunification. Turkey hosts 3.6M Syrians (largest refugee population globally). Regional corridors (Venezuela→Colombia, Ukraine→Russia) shaped by proximity, conflict, labor demand.

Understanding Migration Data

Key Definitions

International Migrant: Person living outside country of birth for 12+ months, regardless of legal status or reason.

Refugee: Person fleeing persecution, war, violence, with international protection under 1951 Geneva Convention (UNHCR mandate).

Internally Displaced Person (IDP): Forced to flee home but remain within national borders. Not legally refugees.

Asylum Seeker: Person seeking refugee status, pending legal determination.

Remittances: Money sent by migrants to family/friends in origin country. Includes formal (banks, money transfer) and informal channels.

Migration Drivers

  • Economic: Wage gaps, labor demand in destination countries
  • Conflict: War, persecution, political instability (Syria, Afghanistan, Ukraine)
  • Climate: Droughts, floods, sea-level rise (21M displaced annually)
  • Family: Reunification, marriage migration
  • Education: International students (6M globally)

Data Challenges

Migration stock data from censuses (every 10 years) interpolated for annual estimates. Irregular migration undercounted—true totals 10-30% higher. Climate migration poorly tracked (internal displacement often temporary). Remittances underestimated due to informal channels (hawala, hand-carrying cash).
