The city hosting the largest number of Syrians is Istanbul, with 511,000 refugees. The number of Syrian refugees in Turkey continues to grow. According to the latest data released by the directorate for migration management, over 3.2 million people are now sheltering on Turkish soil - more than any other country in the world. This figure takes into account all officially registered refugees in possession of a biometric identity card, which is needed to access health, educational and social services in the country. Of these, less than 10 percent live in the refugee camps set up in border areas while the remainder are scattered across Turkey and often live in makeshift and overcrowded accommodation. Last year the authorities started issuing work permits to Syrians, who have temporary protection. However, many NGOs say most refugees continue to work illegally with meager wages and inadequate workplace safety conditions.
