Society for Voluntary Control of Fair and Exhibition Statistics (FKM)
From the very start in 1965, FKM’s basic principles included establishing comparable and reliable exhibition statistics. FKM set up uniform rules for obtaining exhibitor numbers, visitor attendance, exhibition space data and for visitor breakdown statistics. FKM ensures independent auditors check that the rules are adhered to. Because exhibitors and visitors can only plan properly if they can be sure that the data available for the period in question, compared with other exhibitions, is based on uniform criteria.
