 +During the German Reunification period, **calcium carbide** production took place primarily in the new German Länder. A short time later, production there was discontinued and only one producer remained in the old German Länder. In the period under consideration, this producer cut its production by about 50 per cent.

-Since Germany has only one producer, the relevant data must be kept confidential. The only published data consists of that for amounts produced in the former GDR. That data was published, until 1989, by that country's central statistical authority. Those figures were used in combination with existing estimates for 1991 and 1992, to interpolate production in the new German Länder in 1990.+Since Germany has only one producer, the relevant data must be kept confidential.
