An invisible people

Refugees make headlines: internally displaced people do not. IDPs – those who are uprooted from their homes by conflict, violence or disaster, but remain trapped within their country – have, since 1990, outnumbered refugees by two to one. Yet this 40.3 million-strong wave of people is typically overlooked by the global community until it spills across borders, or seas. Displacement is the world's greatest unseen crisis: it's time to invest in solving it.
