This work is an examination of borderless markets where national boundaries are no longer the relevant criteria in making international marketing, economic planning and business decisions. Understanding non-political borders is especially important for products and industries that are culture bound , and those that require local adaptation. Religion is one critical factor that affects economic development, demographic behaviour and general business policies around the world. Over 26,000 statistics are provided for over 70 religious groups covering a number of social, economic and business variables. A significant review of literature is also included.
