İstanbul is the only city that reaches advanced level and its development index doubled Ankara, the second most developed city. Comparing development indexes of the regions, we classified Marmara, West Anatolia, Aegean and Mediterranean close to upper intermediate level. Low-level regions are East Anatolia and Southeast Anatolia regions. In overall Turkey with 3 levels of development could be included in upper intermediate level. Even though 63% of all cities are between 4-6 developments levels the reason that Turkey’s average appears as 3rd level is mainly because high population concentrated in advanced and upper intermediate regions. Finally yet importantly, main problem of these highly developed regions is unemployment.
