World GDP per capita between 1500 and 2003

Template:World economy The world economy or global economy is the economy of all humans in the world, referring to the global economic system, which includes all economic activities conducted both within and between nations, including production, consumption, economic management, work in general, financial transactions and trade of goods and services.<ref>Template:Cite web</ref><ref>"World Economy." – Definition. American English Definition of with Pronunciation by Macmillan Dictionary. N.p., n.d. Web. 2 January 2015.</ref> In some contexts, the two terms are distinct: the "international" or "global economy" is 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 planet 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, genuine data or government cooperation makes calculating 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 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 7.8 billion people (Template:As of)<ref>Template:Cite web</ref><ref>Template:Cite web</ref> have most of their economic activity reflected in these valuations.

Until the middle of the 19th century, global output was dominated by China and India. Waves of the Industrial Revolution in Western Europe and Northern America shifted the shares to the Western Hemisphere. As of 2025, the following 20 countries and 2 collectives have reached an economy of at least US$2 trillion by Gross Domestic Product (GDP) in nominal or Purchasing Power Parity (PPP) terms: Brazil, Canada, China, Egypt, France, Germany, India, Indonesia, Italy, Japan, Mexico, Nigeria, Poland, South Korea, Russia, Saudi Arabia, Spain, Turkey, the United Kingdom, the United States, the European Union and the African Union.<ref name="IMF Data">Template:Cite web</ref><ref>Template:Cite web</ref>

Between 1820 and 2000, global income inequality increased with almost 50%. However, this change occurred mostly before 1950. Afterwards, the level of inequality remained mostly stable. It is important to differentiate between between-country inequality, which was the driving force for this pattern, and within country inequality, which remained largely constant.<ref>Template:Cite journal</ref> Global income inequality peaked approximately in the 1970s, when world income was distributed bimodally into "rich" and "poor" countries with little overlap. Since then, inequality has been rapidly decreasing, and this trend seems to be accelerating. Income distribution is now unimodal, with most people living in middle-income countries.<ref>Template:Cite web</ref>

In the 2000s, a study by the World Institute for Development Economics Research at United Nations University found that the richest 1% of adults owned 40% of global assets, and that the richest 10% of adults accounted for 85% of the world total. The bottom half of the world adult population owned barely 1% of global wealth. Oxfam International reported that the richest 1 percent of people owned 48 percent of global wealth Template:As of,<ref>Oxfam: Richest 1 percent sees share of global wealth jump</ref> and would own more than half of global wealth by 2016.<ref name="NYT-20150119-PC">Template:Cite news</ref> In 2014, Oxfam reported that the 85 wealthiest individuals in the world had a combined wealth equal to that of the bottom half of the world's population, or about 3.5 billion people.<ref>Rigged rules mean economic growth increasingly "winner takes all" for rich elites all over world.

Countries by total wealth (trillions USD), Credit Suisse

• GDP (GWP) (gross world product): (purchasing power parity exchange rates) – $110.06 trillion (2025 estimate)<ref name="IMF Data" />, $117.165 trillion (2023) . The GWP is the combined gross national income of all the countries in the world. When calculating the GWP, add GDP of all countries. Also, GWP shows that imports and exports are equal. Because imports and exports balance exactly when considering the whole world,<ref>Template:Cite web</ref> this also equals the total global gross domestic product (GDP).
• GDP (GWP) (gross world product):<ref>Template:Cite web</ref> (market exchange rates) – $60.69 trillion (2008). The market exchange rates increased from 1990 to 2008. The reason for this increase is the world's advancement in terms of technology.
• GDP<ref>Template:Cite book</ref> (real growth rate): The following part shows the GDP growth rate and the expected value after one year.
  • Developed Economies. A developed country, industrialized country, more developed country (MDC), or more economically developed country (MEDC), is a sovereign state that has a developed economy and advanced technological infrastructure relative to other less industrialized nations. Most commonly, the criteria for evaluating the degree of economic development are gross domestic product (GDP), gross national product (GNP), the per capita income, level of industrialization, amount of widespread infrastructure and general standard of living. Which criteria are to be used and which countries can be classified as being developed are subjects of debate. The GDP of the developed countries is predicted to fall from 2.2% in 2017 to 2.0% in 2018 due to the fall in dollar value.
  • Developing Countries. A developing country is a country with a less developed industrial base (industries) and a low Human Development Index (HDI) relative to other countries. However, this definition is not universally agreed upon. There is also no clear agreement on which countries fit this category. A nation's GDP per capita, compared with other nations, can also be a reference point. In general, the United Nations accepts any country's claim of itself being "developing". The GDP of the developing countries is expected to rise from 4.3% in 2017 to 4.6% in 2018 due to political stability in those countries and advancement in technology.
  • Least developed countries. The least developed countries (LDCs) is a list of developing countries that, according to the United Nations, exhibit the lowest indicators of socioeconomic development, with the lowest Human Development Index ratings of all countries in the world. The concept of LDCs originated in the late 1960s and the first group of LDCs was listed by the UN in its resolution 2768 (XXVI) of 18 November 1971. This is a group of countries that are expected to improve their GDP from 4.8% in 2017 to 5.4% in 2018. The predicted growth is associated advancement in technology and industrialization of those countries for the past decade.
• GDP – per capita: purchasing power parity – $9,300, €7,500 (2005 est.), $8,200, €6,800 (92) (2003), $7,900, €5,000 (2002)
• World median income: purchasing power parity $1,041, €950 (1993)<ref>Template:Cite web</ref>
• GDP – composition by sector: agriculture: 4%; industry: 32%; services: 64% (2004 est.)
• Inflation rate (consumer prices); In economics, inflation is a general rise in the price level in an economy over a period of time, resulting in a sustained drop in the purchasing power of money. When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation reflects a reduction in the purchasing power per unit of money – a loss of real value in the medium of exchange and unit of account within the economy. The opposite of inflation is deflation, a sustained decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index, usually the consumer price index, over time. national inflation rates vary widely in individual cases, from declining prices in Japan to hyperinflation (In economics, hyperinflation is very high and typically accelerating inflation) in several Third World countries (2003):

From the scientific perspective, economic activities are embedded in a web of dynamic, interrelated, and interdependent activities that constitute the natural system of Earth. Novel application of cybernetics in decision-making (such as in decision-making related to process- and product-design and related laws) and direction of human activity (such as economic activity) may make it easier to control modern ecological problems.<ref>Template:Cite journal</ref>

The index includes 11 comparable "dimensions" of well-being:<ref>Template:Cite journal</ref>

1. Housing: housing conditions and spendings (e.g. real estate pricing)
2. Income: household income (after taxes and transfers) and net financial wealth
3. Jobs: earnings, job security and unemployment
4. Community: quality of social support network
5. Education: education and what one gets out of it
6. Environment: quality of environment (e.g. environmental health)
7. Governance: involvement in democracy
8. Health
9. Life Satisfaction: level of happiness
10. Safety: murder and assault rates
11. Work-life balance

Economic studies

To promote exports, many government agencies publish on the web economic studies by sector and country. Among these agencies include the USCS (US DoC) and FAS (USDA) in the United States, the EDC and AAFC in Canada, Ubifrance in France, the UKTI in the United Kingdom, the HKTDC and JETRO in Asia, Austrade and the NZTE in Oceania. Through Partnership Agreements, the Federation of International Trade Associations publishes studies from several of these agencies (USCS, FAS, AAFC, UKTI, and HKTDC) as well as other non-governmental organizations on its website globaltrade.net.
