Gross domestic product (GDP) is a monetary measure of the market value of all the final goods and services produced in a specific time period by a country or countries. GDP is most often used by the government of a single country to measure its economic health. Due to its complex and subjective nature, this measure is often revised before being considered a reliable indicator.
Purchasing power parity (PPP) is a measure of the price of specific goods in different countries and is used to compare the absolute purchasing power of the countries' currencies. PPP is effectively the ratio of the price of a basket of goods at one location divided by the price of the basket of goods at a different location. The PPP inflation and exchange rate may differ from the market exchange rate because of tariffs, and other transaction costs.
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, exchange of financial values and trade of goods and services. 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.
India was one of the largest economies in the world, for about two and a half millennia starting around the end of 1st millennium BC and ending around the beginning of British rule in India.
This is the Economic history of the Indian subcontinent. It includes the economic timeline of the region, from the ancient era to the present, and briefly summarizes the data presented in the Economic history of India and List of regions by past GDP (PPP) articles.
The Indian Century is a neologism suggesting that the 21st century will be dominated by India, as the 20th century is often called the American Century, and the 19th century as Pax Britannica, as the 17-18th centuries dominated by France and the 15-16th centuries dominated by Spain. The phrase is used particularly in the assertion that the economy of India could overtake the economy of the United States and economy of China as the largest national economy in the world, a position it held from 1 to 1500 CE and from 1600 to 1700 CE.
This article lists current estimates of the world population in history. In summary, estimates for the progression of world population since the Late Middle Ages are in the following ranges:
Angus Maddison was a distinguished British economist specialising in quantitative macro economic history, including the measurement and analysis of economic growth and development.
The role and scale of British imperial policy during the British Raj on India's relative decline in global GDP remains a topic of debate among economists, historians, and politicians. Some commentators argue the effect of British rule was negative, and that Britain engaged in a policy of deindustrialisation in India for the benefit of British exporters which left Indians relatively poorer than before British rule. Others argue that Britain's impact on India was either broadly neutral or positive, and that India's declining share of global GDP was due to other factors, such as new mass production technologies or internal ethnic conflict.
The economic history of the world encompasses the development of human economic activity throughout time. It has been estimated that throughout prehistory, the world average GDP per capita was about $158 per annum, and did not rise much until the Industrial Revolution. Cattle were probably the first object or physical thing specifically used in a way similar enough to the modern definition of money, that is, as a medium for exchange.
The Penn World Table (PWT) is a set of national-accounts data developed and maintained by scholars at the University of California, Davis and the Groningen Growth Development Centre of the University of Groningen to measure real GDP across countries and over time. Successive updates have added countries, years (1950-2019), and data on capital, productivity, employment and population. The current version of the database, version 10, thus allows for comparisons of relative GDP per capita, as a measure of standard of living, the productive capacity of economies and their productivity level. Compared to other databases, such as the World Bank's World Development Indicators, the time period covered is larger and there is more data that is useful for comparing productivity across countries and over time.
The Maddison Project, also known as the Maddison Historical Statistics Project, is a project to collate historical economic statistics, such as GDP, GDP per capita, and labor productivity.
