Each year millions of people in low-income countries uproot themselves from rural homes to take their chances in a new setting. But who are these migrants? Where do they go and why?

They indicate an urgent need for policymakers to understand that migration and mobility need not be threats. On the contrary, migration can offer opportunities for economic growth and livelihood security.
