Turkey, this week, has made a radical change in the way it calculates its gross domestic product (GDP), creating a shock effect both regarding its revised results and methodology. 

Turkey's 2015 GDP per capita has increased from $9,130 to 11,014 after the Turkish Statistics Institute (TÜİK) revised how it calculated the figure.

Around 80 million Turks got a nearly 20 percent boost to their average standard of living on Dec. 12 - on paper at least.
