The world economy can be represented in various ways, and broken down in various ways. It is inseparable from the geography and ecology of Earth, e.g. ecoregions which represent different agricultural and resource extraction opportunities, and each have natural capital of their own that provides nature's services to humankind.
Economy - overview
2002 - 2003
Growth in global output (gross world product) (GWP) (in this article defined as GDP converted to US$ through estimated purchasing power parity exchange rates) fell from 4.8% in 2000 to 2.2% in 2001 and 2.7% in 2002. The causes: sluggishness in the EU economy (21.7% of GWP) and in the US economy (21.1% of GWP) ; continued stagnation in the Japanese economy (7.0% of GWP); and spillover effects in the less developed regions of the world.
China, the second-largest economy in the world (12% of GWP), proved an exception, continuing its rapid annual growth, officially announced as 8% but estimated by some observers as perhaps two percentage points lower. India maintained a growth rate of around 6%, and its economic liberalisation pushed it forward into a modern economic superpower. Russia (2.6% of GWP), with 4% growth, continued to make uneven progress, its GDP per capita still only one-third that of the leading industrial nations. The other 14 successor nations of the USSR and the other old Warsaw Pact nations again experienced widely divergent growth rates; the three Baltic nations continued as strong performers, in the 5% range of growth. The developing nations also varied in their growth results, with many countries facing population increases that erode gains in output.
Externally, the nation-state, as a bedrock economic-political institution, is steadily losing control over international flows of people, goods, funds, and technology. Internally, the central government often finds its control over resources slipping as separatist regional movements - typically based on ethnicity - gain momentum, e.g., in many of the successor states of the former Soviet Union, in the former Yugoslavia, in India, and in Indonesia.
The addition of 80 million people each year to an already overcrowded globe is exacerbating the problems of pollution, desertification, underemployment, epidemics, and famine. Because of their own internal problems and priorities, the industrialized countries devote insufficient resources to deal effectively with the poorer areas of the world, which, at least from the economic point of view, are becoming further marginalized.
The euro as the common currency of much of Western Europe in January 1999 , while paving the way for an integrated economic powerhouse, poses economic risks because of varying levels of income and cultural and political differences among the participating nations.
The terrorist attacks on the US on 11 September 2001 accentuate a further growing risk to global prosperity, illustrated, for example, by the reallocation of resources away from investment to anti-terrorist programs. The opening of war in March 2003 between a US-led coalition and Iraq added new uncertainties to global economic prospects.
Growth in global output (gross world product, GWP) rose to 3% in 1999 from 2% in 1998 despite continued recession in Japan, severe financial difficulties in other East Asian countries, and widespread dislocations in several transition economies, notably Russia. The US economy continued its remarkable sustained prosperity, growing at 4.1% in 1999, and accounted for 21% of GWP. Western Europe's economies grew at roughly 2%, not enough to cut deeply into the region's high unemployment; the EU economy produced 22% of GWP. India's economic growth continued at around 6%. China continued its strong growth and accounted for 12% of GWP. Japan grew at only 0.3% in 1999; its share in GWP is 7%. As usual, the 15 successor nations of the USSR and the other old Warsaw Pact nations experienced widely different rates of growth. The developing nations varied widely in their growth results, with many countries facing population increases that eat up gains in output.
GDP - real growth rate: 3.8% (2003), 2.7% (2001)
GDP - per capita: purchasing power parity - $8,200 (92) (2003), $7,900 (2002)

Inflation rate (consumer prices): developed countries 1% to 4% typically; developing countries 5% to 60% typically; national inflation rates vary widely in individual cases, from declining prices in Japan to hyperinflation in several Third World countries (2003)
Industries: dominated by the onrush of technology, especially in computers, robotics, telecommunications, and medicines and medical equipment; most of these advances take place in OECD nations; only a small portion of non-OECD countries have succeeded in rapidly adjusting to these technological forces; the accelerated deployment of new industrial (and agricultural) technology is complicating already grim environmental problems.
