Global marketers face the same environmental factors as they do domestically: culture, economic and technological development, political structure and actions, demography, and natural resources. Cultural considerations include societal values, attitudes and beliefs, language, and customary business practices. A country's economic and technological status depends on its stage of industrial development, which, in turn, affects average family incomes. The political structure is shaped by political ideology and such policies as tariffs, quotas, boycotts, exchange controls, trade agreements, and market groupings. Demographic variables include the size of a population and its age and geographic distribution. A shortage of natural resources also affects the external environment by dictating what is available and at what price.
