To design effective and durable relief programs for refugees and internally displaced people (IDPs), it is essential to understand the nature and context of the challenges the people living in these situations face. That’s why we have recently started to measure consumption and estimate rates of poverty among displaced populations. Through understanding the most acute challenges that vulnerable populations face, relief can be targeted to where support is needed most.
Around 250 million migrants currently live outside their countries of birth, making up approximately 3.5 percent of the world population. Despite the widespread perception of a global migration crisis, this ratio has stayed remarkably stable since the end of the Second World War and lags well behind other major metrics of globalization – international trade, capital flows, tourism etc. A more remarkable statistic is that refugees, at around 15 million, account for 6 percent of the migrant population and only 0.2 percent of world population. In other words, we can fit all refugees in the world in a city with an area of 5000 square kilometers – roughly the size of metropolitan Istanbul or London or Paris – and still have some space left over.
