The World

The world is a common name for the whole of human civilization, specifically human experience, history, or the human condition in general, worldwide, i.e. anywhere on Earth.

The world is the planet Earth and all life upon it, including human civilization.[1] In a philosophical context, the “world” is the whole of the physical Universe, or an ontological world (the “world” of an individual). In a theological context, the world is the material or the profane sphere, as opposed to the celestial, spiritual, transcendent or sacred spheres. “End of the world” scenarios refer to the end of human history, often in religious contexts.

The history of the world is commonly understood as spanning the major geopolitical developments of about five millennia, from the first civilizations to the present. In terms such as world religion, world language, world government, and world war, the term world suggests an international or intercontinental scope without necessarily implying participation of every part of the world.

The world population is the sum of all human populations at any time; similarly, the world economy is the sum of the economies of all societies or countries, especially in the context of globalization. Terms such as “world championship”, “gross world product”, and “world flags” imply the sum or combination of all sovereign states.


Geopolitics (from Greek γῆ  “earth, land” and πολιτική politikḗ “politics”) is the study of the effects of geography (human and physical) on politics and international relations.[1] While geopolitics usually refers to countries and relations between them, it may also focus on two other kinds of states: de facto independent states with limited international recognition and; relations between sub-national geopolitical entities, such as the federated states that make up a federation, confederation or a quasi-federal system.

At the level of international relations, geopolitics is a method of studying foreign policy to understand, explain and predict international political behavior through geographical variables. These include area studies, climate, topography, demography, natural resources, and applied science of the region being evaluated.[2]

Geopolitics focuses on political power in relation to geographic space. In particular, territorial waters and land territory in correlation with diplomatic history. Academically, geopolitics analyses history and social science with reference to geography in relation to politics. Outside academia, a variety of groups offer a geopolitical prognosis, including non-profit groups and for-profit private institutions (such as brokerage houses[3] and consulting companies[4]).Topics of geopolitics include relations between the interests of international political actors, interests focused to an area, space, geographical element or ways, relations which create a geopolitical system.[5]“Critical geopolitics” deconstructs classical geopolitical theories, by showing their political/ideological functions for great powers during and after the age of imperialism.[6]

According to Christopher Gogwilt and other researchers the term is currently being used to describe a broad spectrum of ideas, in a general sense used as “a synonym for internal political relations”, but more specifically “to imply the global structure of such relations”, which builds on “early-twentieth-century term for a pseudoscience of political geography” and other pseudoscientific theories of historical and geographic determinism.

World economy

The world economy or global economy is the economy of the world, considered as the international exchange of goods and services that is expressed in monetary units of account (money).[1] In some contexts, the two terms are distinguished: the “international” or “global economy” being measured separately and distinguished from national economies while the “world economy” is simply an aggregate of the separate countries’ measurements. Beyond the minimum standard concerning value in production, use and exchange the definitions, representations, models and valuations of the world economy vary widely. It is inseparable from the geography and ecology of Earth.

It is common to limit questions of the world economy exclusively to human economic activity and the world economy is typically judged in monetary terms, even in cases in which there is no efficient market to help valuate certain goods or services, or in cases in which a lack of independent research or government cooperation makes establishing figures difficult. Typical examples are illegal drugs and other black market goods, which by any standard are a part of the world economy, but for which there is by definition no legal market of any kind.

However, even in cases in which there is a clear and efficient market to establish a monetary value, economists do not typically use the current or official exchange rate to translate the monetary units of this market into a single unit for the world economy since exchange rates typically do not closely reflect worldwide value, for example in cases where the volume or price of transactions is closely regulated by the government.

Rather, market valuations in a local currency are typically translated to a single monetary unit using the idea of purchasing power. This is the method used below, which is used for estimating worldwide economic activity in terms of real United States dollars or euros. However, the world economy can be evaluated and expressed in many more ways. It is unclear, for example, how many of the world’s 7.13 billion people have most of their economic activity reflected in these valuations.

As of 2017, the following 15 countries or regions have reached an economy of at least US$2 trillion by GDP in nominal or PPP terms: Brazil, China, France, Germany, India, Indonesia, Italy, Japan, South Korea, Mexico, Russia, Turkey, the United Kingdom, the United States and the European Union.
