ANKARA (AA) - Turkey's calendar-adjusted industrial production in December 2018 decreased 9.8 percent from the same month the previous year, the Turkish Statistical Institute (TurkStat) announced on Thursday.
Industrial output is considered a vital indicator for the economy as it is seen as a preliminary gauge for gross domestic product (GDP).
Among three main sub-indices, the manufacturing index saw the highest annual decline in the month, falling 10.8 percent from December 2017.
The mining and quarrying index, and electricity, gas, steam and air conditioning supply index fell by 2.1 percent and 1.2 percent year-on-year respectively.
The term "calendar-adjusted" is used to refer to data without calendar and holiday-originating effects.
