The seasonally adjusted Czech gross domestic product (GDP) was up 0.5 percent in the third quarter of 2017 compared to the previous quarter, and up 5.0 percent compared to the same period last year, according to the preliminary estimates from the Czech Statistical Office (ČSÚ). More detailed data will be released in December. It is the strongest growth in a decade, if 2015 is set aside for being atypical due to one-off factors.
