Internal Migration Statistics

From India’s urban rise driven partly by internal moves to 56.0% of Indonesia’s population living in cities, this page traces how people relocate and what that does to jobs, housing costs, and access to health and education. It also ties labor and poverty effects to measurable gaps between migrants and non-migrants and follows displacement trends such as 8.9 million new internal cases reported in 2023 to show how mobility can both lift opportunity and intensify inequality.

Internal migration is reshaping labor markets and housing pressure in ways that can be measured down to the workforce and the rent. Globally, 2023 brought 8.9 million new internal displacement cases from conflict and disasters, a stark reminder that “moving within a country” is not one story but many. This post brings together the latest cross-country statistics on who moves, where they end up, and what changes when access to jobs, services, and affordable housing shifts.
