Types of migration

Read this step

Economic migration: People moving in search of better economic opportunities. The most common type. Mexican migration to the United States, South Asian migration to the Persian Gulf, and African migration to Europe are major examples.
Refugees: People fleeing persecution, war, or other serious threats. The 1951 UN Refugee Convention establishes the rights of refugees. As of the 2020s, approximately 30 million people are formally classified as refugees, with millions more internally displaced.
Climate migration: People moving because of climate-driven changes (drought, sea level rise, extreme weather). Hard to count precisely but expected to grow dramatically.
