The image of the lifeless little boy, facedown on a beach, highlights the deadly risks for Syrian refugees.

For three years, a civil war has raged in the country, causing the deaths of more than 200,000 people, and sending people fleeing from their homes.

The country of about 23 million is falling apart, with almost half the population on the run. At least 4.1 million people have left the country and another 7.6 million are internally displaced.

Mashable looked at the numbers to put them in context.

The map below shows the rise of the refugee population in Syria's neighboring countries of Egypt, Libya, Iraq, Lebanon and Jordan.

In 2015, five of these countries bore the bulk of the 4 million refugees who have fled Syria since 2011, including 1.9 million registered Syrian refugees in Turkey, 1.1 million in Lebanon, 629,000 in Jordan, 250,000 in Iraq and 130,000 in Egypt. Europe has received a mere fraction of refugees in comparison.
