What Makes an Event a Mega-Event? Definitions and Sizes

Abstract

There is considerable ambiguity about what makes an event a mega-event. Intervening in this debate, this paper develops a definition and classification scheme for mega-events. On the basis of a review of existing definitions, it proposes four constitutive dimensions of mega-events: visitor attractiveness, mediated reach, costs and transformative impact. The paper develops indicators for each dimension and maps onto these four dimensions a sample of the latest editions of nine large events: Expo, Summer and Winter Olympics, Football World Cup, European Football Championship, Asian Games, Commonwealth Games, Pan American Games, Universiade. From this, it develops a multi-dimensional, point-based classification scheme of large events according to size, distinguishing between major events, mega-events and the recently emerging class of giga-events. Concluding, it identifies the need for more systematic data on the size, costs and impacts of a broad range of large-scale events over time.
