The Syrian crisis has now become one of the largest humanitarian crises of our time. The numbers are staggering. About half of the Syrian pre-conflict population has been displaced, over 200,000 people have been killed, millions of Syrians have been injured or traumatized and millions more have fled to neighboring countries and elsewhere. Yet, we know surprisingly little about the actual living conditions of those who are suffering from the crisis. For the people who have remained in Syria, information is either very scarce or unavailable. For the people affected by the Syrian crisis who have migrated to Europe, we have mostly anecdotal information that mixes victims of the Syrian crisis with other types of migrants. For those Syrians who have fled to neighboring countries and registered as refugees, we have a substantial amount of information but to date this information has been little exploited to study the welfare of refugees.
