Here are the facts: 65 million people displaced from their homes by violence and persecution last year. If it was a country, that would be the 21st largest country in the world. Most of those people, about 40 million, stay within their own home country, but 25 million are refugees. That means they cross a border into a neighboring state. Most of them are living in poor countries, relatively poor or lower-middle-income countries, like Lebanon. In Lebanon, one in four people is a refugee, a quarter of the whole population. And refugees stay for a long time. The average length of displacement is 10 years. I went to what was the world’s largest refugee camp, in eastern Kenya. It’s called Dadaab. It was built in 1991-92 as a "temporary camp" for Somalis fleeing the civil war. I met Silo. And naïvely I said to Silo, "Do you think you’ll ever go home to Somalia?" And she said, "What do you mean, go home? I was born here." And then when I asked the camp management how many of the 330,000 people in that camp were born there, they gave me the answer: 100,000. That’s what long-term displacement means.
