Purchasing power parity in the context of "Purchasing power"

Gross domestic product (GDP) is a monetary measure of the total market value of all the final goods and services produced and rendered in a specific time period by a country or countries. GDP is often used to measure the economic activity of a country or region. The major components of GDP are consumption, government spending, net exports (exports minus imports), and investment. Changing any of these factors can increase the size of the economy. For example, population growth through mass immigration can raise consumption and demand for public services, thereby contributing to GDP growth. However, GDP is not a measure of overall standard of living or well-being, as it does not account for how income is distributed among the population. A country may rank high in GDP but still experience jobless growth depending on its planned economic structure and strategies. Dividing total GDP by the population gives an idealized rough measure of GDP per capita. Several national and international economic organizations, such as the OECD and the International Monetary Fund, maintain their own definitions of GDP.

GDP is often used as a metric for international comparisons as well as a broad measure of economic progress. It serves as a statistical indicator of national development and progress. Total GDP can also be broken down into the contribution of each industry or sector of the economy. Nominal GDP is useful when comparing national economies on the international market using current exchange rate. To compare economies over time inflation can be adjusted by comparing real instead of nominal values. For cross-country comparisons, GDP figures are often adjusted for differences in the cost of living using purchasing power parity (PPP). GDP per capita at purchasing power parity can be useful for comparing living standards between nations.

The gross world product (GWP), also known as gross world income (GWI), is the combined gross national income (previously, the "gross national product") 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.

The cost of living is the cost of maintaining a certain standard of living for an individual or a household. Changes in the cost of living over time can be measured in a cost-of-living index. Cost of living calculations are also used to compare the cost of maintaining a certain standard of living in different geographic areas. Differences in the cost of living between locations can be measured in terms of purchasing power parity rates. A sharp rise in the cost of living can trigger a cost of living crisis, where purchasing power is lost and, for some people, their previous lifestyle is no longer affordable.

The link between income and health is well-established. People who are facing poverty are less likely to seek regular and professional medical advice, receive dental care, or resolve health issues. The cost of prescription medicine is often cited as a metric in cost of living research and consumer price indices. Cost of living pressures may lead to household energy insecurity or fuel poverty as well as housing stress.As the cost of living steadily increases, the amount of household income necessary for a financially comfortable life subsequently increases, thus resulting in the number of people who do possess the privilege of a comfortable financial situation decreasing over time. Said privileges of financial comfort become more exclusive to higher classes as the cost of living becomes difficult to afford for more and more people.

A country's gross domestic product (GDP) at purchasing power parity (PPP) per capita is the PPP value of all final goods and services produced within an economy in a given year, divided by the average (or mid-year) population for the same year. This is similar to nominal GDP per capita but adjusted for the cost of living in each country.

In 2023, the estimated average GDP per capita (PPP) of all of the countries was Int$22,452. For rankings regarding wealth, see list of countries by wealth per adult.

The international dollar (int'l dollar or intl dollar, symbols Int'l$., Intl$., Int$), also known as Geary–Khamis dollar (symbols G–K$ or GK$), is a hypothetical unit of currency that has the same purchasing power parity that the U.S. dollar had in the United States at a given point in time. It is mainly used in economics and financial statistics for various purposes, most notably to determine and compare the purchasing power parity and gross domestic product of various countries and markets. The year 1990 or 2000 is often used as a benchmark year for comparisons that run through time. The unit is often abbreviated, e.g. 2000 US dollars or 2000 International$ (if the benchmark year is 2000).

It is based on the twin concepts of purchasing power parities (PPP) of currencies and the international average prices of commodities. It shows how much a local currency unit is worth within the country's borders. It is used to make comparisons both between countries and over time. For example, comparing per capita gross domestic product (GDP) of various countries in international dollars, rather than based simply on exchange rates, provides a more valid measure to compare standards of living. It was proposed by Roy C. Geary in 1958 and developed by Salem Hanna Khamis between 1970 and 1982.

The People's Republic of China has a developing mixed socialist market economy, incorporating industrial policies and strategic five-year plans. China has the world's second-largest economy by nominal GDP and since 2016 has been the world's largest economy when measured by purchasing power parity (PPP). China accounted for 19% of the global economy in 2022 in PPP terms, and around 18% in nominal terms in 2022. The economy consists of state-owned enterprises (SOEs) and mixed-ownership enterprises, as well as a large domestic private sector which contribute approximately 60% of the GDP, 80% of urban employment and 90% of new jobs.

China is the world's largest manufacturing industrial economy and exporter of goods. China is widely regarded as the "powerhouse of manufacturing", "the factory of the world" and the world's "manufacturing superpower". Its production exceeds that of the nine next largest manufacturers combined. However, exports as a percentage of GDP have steadily dropped to just around 20%, reflecting its decreasing importance to the Chinese economy. Nevertheless, it remains the largest trading nation in the world and plays a prominent role in international trade. Manufacturing has been transitioning toward high-tech industries such as electric vehicles, renewable energy, telecommunications and IT equipment, and services has also grown as a percentage of GDP. However, recent research indicates that China’s Total factor productivity (TFP) growth has slowed significantly. IMF estimates show that TFP growth declined from approximately 3.7% in the 2000s to around 1.9% during 2010–2019. Structural reforms and technological progress in manufacturing between 2010 and 2020 contributed only modestly to productivity gains. Additionally, a 2024–2025 IMF working paper finds that factor misallocation resulting from industrial and regulatory policies implemented since the early 2010s reduces China’s aggregate TFP by roughly 1.2% annually. IMF research suggests that while China’s state-led push for high-tech self-reliance since 2013 has supported rapid innovation, it has been accompanied by efficiency losses. Policy measures, including targeted state subsidies appear to favor politically connected firms, crowd out competition, and lead to overcapacity, undermining overall productivity. China is the world's largest high technology exporter. As of 2023, the country spends around 2.6% of GDP to advance research and development across various sectors of the economy. It is also the world's second-largest importer of goods. China is a net importer of services products.

Taiwan is a highly developed free-market economy. It is the 8th largest in Asia and 21st-largest in the world by purchasing power parity, allowing Taiwan to be included in the advanced economies group by the International Monetary Fund. Taiwan is notable for its rapid economic development from an agriculture-based society to an industrialized, high-income country. This economic growth has been described as the Taiwan Miracle. It is gauged in the high-income economies group by the World Bank. Taiwan is one of the leading producers of computer microchip and high-tech electronics.

Industrialisation (UK) or industrialization (US) is "the period of social and economic change that transforms a human group from an agrarian and feudal society into an industrial society. This involves an extensive reorganisation of an economy for the purpose of manufacturing." Industrialisation is associated with an increase in polluting industries heavily dependent on fossil fuels. With the increasing focus on sustainable development and green industrial policy practices, industrialisation increasingly includes technological leapfrogging, with direct investment in more advanced, cleaner technologies.

The reorganisation of the economy has many unintended consequences both economically and socially. As industrial workers' incomes rise, markets for consumer goods and services of all kinds tend to expand and provide a further stimulus to industrial investment and economic growth. Moreover, family structures tend to shift as extended families tend to no longer live together in one household, location or place.
