Turkey's refugees are living in at least 21 camps scattered across four border provinces.

The Turkish disaster management agency has estimated that the number of Syrian refugees in Turkey actually exceeds the UN's figure — with 400,000 living outside the refugee camps.

The government had spent an estimated $2 billion on the refugee situation as of August 2013, according to Prime Minister Tayyip Erdogan.

Syria's refugees have fled from all over the country, according to the Office of the United Nations High Commissioner for Refugees.

Aid groups also estimate that more than 4.25 million people have been displaced inside Syria itself.

Lebanon

This total includes almost 50,000 Syrians who have been in contact with UNHCR but are not yet registered as of April 2.

Lebanon has a normal population of 4.25 million. The government has not built formal refugee camps.

The UN estimated in April 2014 that 267,185 refugees have settled in northern Lebanon, with another 341,516 in the eastern Bekaa area. Beirut hosts an estimated 265,457 refugees and there are another 122,128 in the country's south.

More than 100,000 refugees were housed at the Za'atari refugee camp alone, as of April 2014. This makes Za'atari, which opened in July 2012, unofficially Jordan's fifth largest city.

A new camp has been completed in Azraq, a border town due east of the capital, Amman. It stands empty for the time being, but is built to house another 130,000 people.

Jordan's government has estimated that hosting the refugees cost the country's economy $2 billion in 2013.

Iraq

Syria took in more than 1 million refugees from Iraq while that country was embroiled in its bloody conflict over the past decade. Now the tide of refugees has reversed course.

In addition to Syrians fleeing the conflict, the UN says thousands of Iraqis have come home since mid-July 2012. (Almost 900,000 Iraqis have already returned in recent years.)
