The gross world product (GWP), also known as gross world income (GWI), is the combined gross national income of all the countries in the world. Because imports and exports balance exactly when considering the whole world, this also equals the total global gross domestic product (GDP). According to the World Bank, the 2013 nominal GWP was approximately 75.59 trillion United States dollars. In 2017, according to the CIA's World Factbook, the GWP was around $80.27 trillion in nominal terms and totaled approximately 127.8 trillion international dollars in terms of purchasing power parity (PPP). The per capita PPP GWP in 2017 was approximately 17,500 international dollars according to the World Factbook. According to the World Bank, the 2020 GWP in current dollars was approximately $84.705 trillion.
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 market basket 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, financial transactions 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.
The economies of Canada and the United States are similar because both are developed countries. While both countries feature in the top ten economies in the world in 2022, the U.S. is the largest economy in the world, with US$24.8 trillion, with Canada ranking ninth at US$2.2 trillion.
India was one of the richest countries in the world, for about two and a half millennia starting around the end of 1st millennium BC and ending around the beginning of British rule in India.
The economy of the Organisation of Islamic Cooperation (OIC) combines the economies of 56* member states. 49* are predominantly Muslim states. As of 2013, the combined GDP (nominal) of 48* Muslim majority countries was US$ 12.97 trillion. As of 2016, they contributed 8% of the world's total. Those 57* OIC countries have a combined GDP of US$ 23.948trillion. The largest economic country based on total PPP and Nominal GDP is Indonesia. The richest country on the basis of GDP per capita at PPP is Qatar, with incomes exceeding $133,357 per capita. On the basis of per capita GDP, Qatar is also the richest country, with incomes exceeding US$68,977 per capita. According to a report by Salam Standard, the GDP impact of the world’s Muslim tourism sector exceeded $138 billion in 2015, generating 4.3 million jobs and contributing more than $18 billion in tax revenue.
Angus Maddison was a distinguished British economist specialising in quantitative macro economic history, including the measurement and analysis of economic growth and development.
Income in India discusses the financial state in India. With rising economic growth and prosperity, India's income is also rising rapidly. As an overview, India's per capita net national income or NNI was around Rs. 98,374 in 2022-23. The per-capita income is a crude indicator of the prosperity of a country. In contrast, the gross national income at constant prices stood at over 128 trillion rupees. The same year, GRI growth rate at constant prices was around 6.6 percent. While GNI and NNI are both indicators for a country's economic performance and welfare, the GNI is related to the GDP or the Gross Domestic Product plus the net receipts from abroad, including wages and salaries, property income, net taxes and subsidies receivable from abroad. On the other hand, the NNI of a country is equal to its GNI net of depreciation.
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.
Since independence in 1947, the economy of Pakistan has emerged as a semi-industrialized one, the on textiles, agriculture, and food production, though recent years have seen a push towards technological diversification. Pakistan's GDP growth has been gradually on the rise since 2012 and the country has made significant improvements in its provision of energy and security. However, decades of corruption and internal political conflict have usually led to low levels of foreign investment and underdevelopment.
The economy of South Asia comprises 2 billion people living in eight countries. The Indian subcontinent was historically one of the richest regions in the world, comprising 25% of world GDP as recently as 1700, but experienced significant de-industrialisation and a doubling of extreme poverty during the colonial era of the late 18th to mid-20th century. In the post-colonial era, South Asia has grown significantly, with India advancing because of economic liberalisation from the 1980s onwards, and extreme poverty now below 15% in the region. South Asia has been the fastest-growing region of the world since 2014.
