GDP is often used as a metric for
international comparisons as well as a
broad measure of economic progress. It is often considered to be the world's most powerful statistical indicator of national development and progress. The GDP can be divided by the total population to obtain the average
GDP per capita. 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 according to the

History

Sir
William Petty came up with a concept of GDP, to calculate the
tax burden, and argue landlords were unfairly taxed during
warfare between the Dutch and the English between 1652 and 1674.
Charles Davenant developed the method further in 1695.
The modern concept of GDP was first developed by
Simon Kuznets for a 1934
U.S. Congress report, where he warned against its use as a measure of welfare (see below under ''
limitations and criticisms'').
[Congress commissioned Kuznets to create a system that would measure the nation's productivity in order to better understand how to tackle the ]Great Depression
The Great Depression was a severe global economic downturn from 1929 to 1939. The period was characterized by high rates of unemployment and poverty, drastic reductions in industrial production and international trade, and widespread bank and ...

Bretton Woods Conference in 1944, GDP became the main tool for measuring a country's economy. At that time
gross national product (GNP) was the preferred estimate, which differed from GDP in that it measured production by a country's citizens at home and abroad rather than its "resident institutional units" (see

definition above). The switch from GNP to GDP in the United States occurred in 1991. The role that measurements of GDP played in World War II was crucial to the subsequent political acceptance of GDP values as indicators of national development and progress. A crucial role was played here by the
U.S. Department of Commerce under
Milton Gilbert where ideas from Kuznets were embedded into

The history of the concept of GDP should be distinguished from the history of changes in many ways of estimating it. The value added by firms is relatively easy to calculate from their accounts, but the value added by the
public sector, by financial industries, and by
intangible asset creation is more complex. These activities are increasingly important in developed economies, and the international conventions governing their estimation and their inclusion or exclusion in GDP regularly change in an attempt to keep up with industrial advances. In the words of one academic economist, "The actual number for GDP is, therefore, the product of a vast patchwork of statistics and a complicated set of processes carried out on the raw data to fit them to the conceptual framework."
China
China, officially the People's Republic of China (PRC), is a country in East Asia. With population of China, a population exceeding 1.4 billion, it is the list of countries by population (United Nations), second-most populous country after ...
officially adopted GDP in 1993 as its indicator of economic performance. Previously, China had relied on a Marxist-inspired national accounting system.
Determining gross domestic product (GDP)
GDP can be determined in three ways, all of which should, theoretically, give the same result. They are the production (or output or value added) approach, the income approach, and the speculated expenditure approach. It is representative of the total output and income within an economy.
The most direct of the three is the production approach, which sums the outputs of every class of enterprise to arrive at the total. The expenditure approach works on the principle that all of the products must be bought by somebody, therefore the value of the total product must be equal to people's total expenditures in buying things. The income approach works on the principle that the incomes of the productive factors ("producers", colloquially) must be equal to the value of their product, and determines GDP by finding the sum of all producers' incomes.
Production approach
Also known as the Value Added Approach, it calculates how much value is contributed at each stage of production.
This approach mirrors the
OECD
The Organisation for Economic Co-operation and Development (OECD; , OCDE) is an international organization, intergovernmental organization with 38 member countries, founded in 1961 to stimulate economic progress and international trade, wor ...
(Organisation for Economic Co-operation and Development) definition given above.
# Estimate the gross value of domestic output out of the many various economic activities;
# Determine the
intermediate consumption, i.e., the cost of material, supplies and services used to produce final goods or services.
# Deduct intermediate consumption from gross value to obtain the gross value added.
Gross value added = gross value of output – value of intermediate consumption.
Value of output = value of the total sales of goods and services plus the value of changes in the inventory.
The sum of the gross value added in the various economic activities is known as "GDP at factor cost".
GDP at factor cost plus indirect taxes less subsidies on products = "GDP at producer price".
For measuring the output of domestic product, economic activities (i.e. industries) are classified into various sectors. After classifying economic activities, the output of each sector is calculated by any of the following two methods:
# By multiplying the output of each sector by their respective market price and adding them together
# By collecting data on gross sales and inventories from the records of companies and adding them together
The value of output of all sectors is then added to get the gross value of output at factor cost. Subtracting each sector's intermediate consumption from gross output value gives the GVA (=GDP) at factor cost. Adding indirect tax minus subsidies to GVA (GDP) at factor cost gives the "GVA (GDP) at producer prices".
Income approach

The second way of estimating GDP is to use "the sum of primary incomes distributed by resident producer units".
If GDP is calculated this way it is sometimes called gross domestic income (GDI), or GDP (I). GDI should provide the same amount as the expenditure method described later. By definition, GDI is equal to GDP. In practice, however, measurement errors will make the two figures slightly off when reported by national statistical agencies.
This method measures GDP by adding incomes that firms pay households for factors of production they hire – wages for labour, interest for capital, rent for land and profits for entrepreneurship.
The US "National Income and Product Accounts" divide incomes into five categories:
# Wages, salaries, and supplementary labor income
# Corporate profits
# Interest and miscellaneous investment income
# Income earned by sole proprietors and from the Housing subsector (net of expenses)
# Net income from transfer payments from businesses
These five income components sum to net domestic income at factor cost.
Two adjustments must be made to get GDP:
# Taxes on production and imports minus subsidies are added to get from factor cost to market prices.
# Depreciation (or
capital consumption allowance) is added to get from net domestic product to gross domestic product.
Total income can be subdivided according to various schemes, leading to various formulae for GDP measured by the income approach. A common one is:
: GDP = + + +
* Compensation of employees (COE) measures the total remuneration to employees for work done. It includes wages and salaries, as well as employer contributions to
social security
Welfare spending is a type of government support intended to ensure that members of a society can meet basic human needs such as food and shelter. Social security may either be synonymous with welfare, or refer specifically to social insurance ...
and other such programs.
* Gross operating surplus (GOS) is the surplus due to owners of incorporated businesses. Often called
profits, although only a subset of total costs are subtracted from
gross output
In economics, gross output (GO) is a measure of the value of production of new goods and services during an accounting period. Gross output represents the total value of ''sales'' by producing enterprises (their gross revenue or turnover) in an ac ...
to calculate GOS.
* Gross mixed income (GMI) is the same measure as GOS, but for unincorporated businesses. This often includes most small businesses.
The sum of COE, GOS and GMI is called total factor income; it is the income of all of the factors of production in society. It measures the value of GDP at factor (basic) prices. The difference between basic prices and final prices (those used in the expenditure calculation) is the total taxes and subsidies that the government has levied or paid on that production. So adding taxes less subsidies on production and imports converts GDP(I) at
factor cost to GDP(I) at final prices.
Total factor income is also sometimes expressed as:
: ''Total factor income'' = ''employee compensation'' + ''corporate profits'' + ''proprietor's income'' + ''rental income'' + ''net interest''
Expenditure approach
The third way to estimate GDP is to calculate the sum of the final uses of goods and services (all uses except intermediate consumption) measured in purchasers' prices.
Market goods that are produced are purchased by someone. In the case where a good is produced and unsold, the standard accounting convention is that the producer has bought the good from themselves. Therefore, measuring the total expenditure used to buy things is a way of measuring production. This is known as the expenditure method of calculating GDP.
Components of GDP by expenditure

GDP (Y) is the sum of consumption (C), investment (I), government expenditures (G) and net exports (X − M).
: Y = C + I + G + (X − M)
Here is a description of each GDP component:
* C (consumption) is normally the largest GDP component in the economy, consisting of private expenditures in the economy (
household final consumption expenditure). These personal expenditures fall under one of the following categories:
durable goods, nondurable goods, and services. Examples include food, rent, jewelry, gasoline, and medical expenses, but not the purchase of new housing.
* I (investment) includes, for instance, business investment in equipment, but does not include exchanges of existing assets. Examples include the construction of a new
mine, the purchase of software, or the purchase of machinery and equipment for a factory. Spending by households (not the government) on new houses is also included in investment. In contrast to its colloquial meaning, "investment" in GDP does not mean purchases related to financial investments. Buying
financial products is classed as '
saving', as opposed to investment. This avoids double-counting: if one buys shares in a company, and the company uses the money received to build a plant, purchase equipment, etc., the amount will be counted toward GDP when the company spends the money on those things; to also count it when one gives it to the company would be to count two times an amount that only corresponds to one group of products. Buying
bonds or companies'
equity shares is a swapping of
deeds, a transfer of claims on future production, not directly an expenditure on products; buying an existing building will involve a positive investment by the buyer and a negative investment by the seller, netting to zero overall investment.
* G (government spending) is the sum of
government expenditures on
final goods and services. It includes salaries of
public servants, purchases of weapons for the military and any investment expenditure by a government. It does not include any
transfer payments, such as
social security
Welfare spending is a type of government support intended to ensure that members of a society can meet basic human needs such as food and shelter. Social security may either be synonymous with welfare, or refer specifically to social insurance ...
or
unemployment benefits. Analyses outside the US will often treat government investment as part of ''investment'' rather than ''government spending''.
* X (exports) represents gross exports. GDP captures the amount a country produces, including goods and services produced for other nations' consumption, therefore exports are added.
* M (imports) represents gross imports. Imports are subtracted since imported goods will be included in the terms G, I, or C, and must be deducted to avoid counting foreign
supply as domestic.
C, I, and G are expenditures on
final goods and services; expenditures on intermediate goods and services do not count. (Intermediate goods and services are those used by businesses to produce other goods and services within the accounting year.) So for example if a
car manufacturer buys
auto parts, assembles the car and sells it, only the final car sold is counted towards the GDP. Meanwhile, if a person buys replacement auto parts to install them on their car, those are counted towards the GDP.
According to the U.S. Bureau of Economic Analysis, which is responsible for calculating the national accounts in the United States, "In general, the source data for the expenditures components are considered more reliable than those for the income components
ee income method, above"
Encyclopedia Britannica records an alternate way of measuring exports minus imports: notating it as the single variable NX.
Nominal GDP and real GDP
The raw GDP figure given by the equations above is called the nominal, historical, or current GDP. When comparing GDP figures from one year to another, compensating for changes in the value of money—for the effects of inflation or deflation is desirable. To make it more meaningful for year-to-year comparisons, a nominal GDP may be multiplied by the ratio between the value of money in the year the GDP was measured and the value of money in a base year.
For example, suppose a country's GDP in 1990 was and its GDP in 2000 was . Suppose also that inflation had halved the value of its currency over that period. To meaningfully compare its GDP in 2000 to its GDP in 1990, we could multiply the GDP in 2000 by one-half, to make it relative to 1990 as a base year. The result would be that the GDP in 2000 equals × = , ''in 1990 monetary terms.'' We would see that the country's GDP had realistically increased 50
percent over that period, not 200 percent, as it might appear from the raw GDP data. The GDP adjusted for changes in money value in this way is called the
real GDP.
The factor used to convert GDP from current to constant values in this way is called the ''
GDP deflator''. Unlike
consumer price index
A consumer price index (CPI) is a statistical estimate of the level of prices of goods and services bought for consumption purposes by households. It is calculated as the weighted average price of a market basket of Goods, consumer goods and ...
, which measures inflation or deflation in the price of household consumer goods, the GDP deflator measures changes in the prices of all domestically produced goods and services in an economy including investment goods and government services, as well as household consumption goods.
National measurement
Within each country GDP is normally measured by a national government statistical agency, as
private sector
The private sector is the part of the economy which is owned by private groups, usually as a means of establishment for profit or non profit, rather than being owned by the government.
Employment

System of National Accounts'' (2008), which was prepared by representatives of the

SNA2008 provides a set of rules and procedures for the measurement of national accounts. The standards are designed to be flexible, to allow for differences in local statistical needs and conditions.
GDP per capita
GDP can be adjusted for population growth, also called ''Per-capita GDP'' or ''GDP per person''. This measures the average production of a person in the country. The major advantage of GDP per capita as an indicator of the standard of living is that it is measured frequently, widely, and consistently. It is measured frequently in that most countries provide information on GDP every quarter, allowing trends to be seen quickly. It is measured widely in that some measure of GDP is available for almost every country in the world, allowing inter-country comparisons. It is measured consistently in that the technical definition of GDP is relatively consistent among countries.
It can be argued that GDP per capita is an indicator of standard of living.
As a result, GDP per capita as a standard of living is a continued usage because most people have a fairly accurate idea of what it is and know it is tough to come up with quantitative measures for such constructs as happiness, quality of life, and well-being.
From the perspective of environmental, social and governance (ESG) measures, GDP per capita trends can be influenced by factors such as gender parity and elements of regulatory quality. The change in number of MSMEs (Micro, Small, and Medium Enterprises) in the Philippines from 2008 through 2021 would be an example of elements such as the per capita gross domestic product and unemployment rate having significant effect on a developing country with mixed economy.

Economic growth

Real GDP can be used to calculate the GDP growth rate, which indicates how much a country's production has increased (or decreased, if the growth rate is negative) compared to the previous year, typically expressed as
percentage change. The economic growth can be expressed as:

PPP)

List of countries by real GDP per capita growth

List of countries by GNI per capita growth
Relation to Gross national income
GDP can be contrasted with the
Gross national income (GNI) also known as gross national product (GNP). The difference is that GDP defines its scope according to location, while GNI defines its scope according to ownership. In a global context,
world GDP and world GNI are, therefore, equivalent terms.
GDP is a product produced within a country's borders; GNI is product produced by enterprises owned by a country's citizens. The two would be the same if all of the productive enterprises in a country were owned by its own citizens and those citizens did not own productive enterprises in any other countries. In practice, however, foreign ownership makes GDP and GNI non-identical. Production within a country's borders, but by an enterprise owned by somebody outside the country, counts as part of its GDP but not its GNI; on the other hand, production by an enterprise located outside the country, but owned by one of its citizens, counts as part of its GNI but not its GDP.
For example, the GNI of the
US is the value of output produced by American-owned firms, regardless of where the firms are located. Similarly, if a country becomes increasingly in debt, and spends large amounts of income servicing this debt this will be reflected in a decreased GNI but not a decreased GDP. Similarly, if a country sells off its resources to entities outside their country this will also be reflected over time in decreased GNI, but not decreased GDP. This would make the use of GDP more attractive for politicians in countries with increasing national debt and decreasing assets.
Gross national income (GNI) equals GDP plus income receipts from the rest of the world minus income payments to the rest of the world.
In 1991, the
United States
The United States of America (USA), also known as the United States (U.S.) or America, is a country primarily located in North America. It is a federal republic of 50 U.S. state, states and a federal capital district, Washington, D.C. The 48 ...
switched from using GNP to using GDP as its primary measure of production. The relationship between United States GDP and GNP is shown in table 1.7.5 of the ''
National Income and Product Accounts''.
You find other examples that amplify differences between GDP and GNI by comparing indicators of developed and developing countries. The GDP of Japan for 2020 was 5.05559 trillion. Predictably, as a developed country, we see a higher GNI of 5.16915 trillion for the same year. An increase of 113.560 million. This being indicative of the production level in the country being higher than that of national production. On the other hand, the case with
Armenia
Armenia, officially the Republic of Armenia, is a landlocked country in the Armenian Highlands of West Asia. It is a part of the Caucasus region and is bordered by Turkey to the west, Georgia (country), Georgia to the north and Azerbaijan to ...
is the opposite with its GNI in 2023 being lower than its GDP by 3.85 billion. This shows us countries receive investments and foreign aid from abroad.
Limitations and criticisms
Simon Kuznets, the economist who developed the first comprehensive set of measures of national income, stated in his second report to the U.S. Congress in 1937, in a section titled "Uses and Abuses of National Income Measurements":
The valuable capacity of the human mind to simplify a complex situation in a compact characterization becomes dangerous when not controlled in terms of definitely stated criteria. With quantitative measurements especially, the definiteness of the result suggests, often misleadingly, a precision and simplicity in the outlines of the object measured. Measurements of national income are subject to this type of illusion and resulting abuse, especially since they deal with matters that are the center of conflict of opposing social groups where the effectiveness of an argument is often contingent upon oversimplification. ..
All these qualifications upon estimates of national income as an index of productivity are just as important when income measurements are interpreted from the point of view of economic welfare. But in the latter case additional difficulties will be suggested to anyone who wants to penetrate below the surface of total figures and market values. Economic welfare cannot be adequately measured unless the personal distribution of income is known. And no income measurement undertakes to estimate the reverse side of income, that is, the intensity and unpleasantness of effort going into the earning of income. The welfare of a nation can, therefore, scarcely be inferred from a measurement of national income as defined above.
In 1962, Kuznets stated:
Distinctions must be kept in mind between quantity and quality of growth, between costs and returns, and between the short and long run. Goals for more growth should specify more growth of what and for what.
GDP as initially defined includes spending on goods and services that would shrink if underlying problems were solved or reduced - for example, medical care, crime-fighting, and the military. During World War II, Kuznets came to argue that military spending should be excluded during peacetime. This idea did not become popular; these activities are tracked because they fit into macroeconomic models (e.g. military spending uses up capital and labor).
Ever since the development of GDP, multiple observers have pointed out limitations of using GDP as the overarching measure of economic and social progress. Furthermore, the GDP does not consider human health nor the educational aspect of a population.
Instances of GDP measures have been considered numbers that are artificial constructs. American politician
Robert F. Kennedy criticized GDP (or GNI), listing many examples of bad things it does count and good things it does not count:
Unpaid work
GDP excludes the value of household and other
unpaid work. Some, including
Martha Nussbaum, argue that this value should be included in measuring GDP, as household labor is largely a
substitute for goods and services that would otherwise be purchased with money. Even under conservative estimates, the value of unpaid labor in Australia has been calculated to be over 50% of the country's GDP. A later study analyzed this value in other countries, with results ranging from a low of about 15% in Canada (using conservative estimates) to high of nearly 70% in the United Kingdom (using more liberal estimates). For the
United States
The United States of America (USA), also known as the United States (U.S.) or America, is a country primarily located in North America. It is a federal republic of 50 U.S. state, states and a federal capital district, Washington, D.C. The 48 ...
, the value was estimated to be between about 20% on the low end to nearly 50% on the high end, depending on the methodology being used. Because many public policies are shaped by GDP calculations and by the related field of
national accounts, public policy might differ if unpaid work were included in total GDP. Some economists have advocated for changes in the way public policies are formed and implemented.
Some have pointed out that GDP did not adapt to sociotechnical changes to give a more accurate picture of the modern economy and does not encapsulate the
value of new activities such as delivering price-free information and entertainment on
social media

Diane Coyle explained that GDP excludes much unpaid work, writing that "many people contribute free digital

that can substitute for marketed equivalents, and it clearly has great economic value despite a price of zero", which constitutes a common criticism "of the reliance on GDP as the measure of economic success" especially after the emergence of the
digital economy.
GDP and assets
The UK's
Natural Capital Committee highlighted the shortcomings of GDP in its advice to the
UK Government in 2013, pointing out that GDP "focuses on flows, not stocks. As a result, an economy can run down its assets yet, at the same time, record high levels of GDP growth, until a point is reached where the depleted assets act as a check on future growth". They then went on to say that "it is apparent that the recorded GDP growth rate overstates the
sustainable growth rate. Broader measures of wellbeing and wealth are needed for this and there is a danger that short-term decisions based solely on what is currently measured by national accounts may prove to be costly in the long-term".
Health
In 2013 scientists reported that large
improvements in

Health has a variety of definitions, which have been used for different purposes over time. In general, it refers to physical and emotional well-being, especially that associated with normal functioning of the human body, absent of disease, p ...
only lead to modest long-term increases in GDP per capita. After developing an abstract metric similar to GDP, the
Center for Partnership Studies highlighted that GDP "and other metrics that reflect and perpetuate them" may not be useful for facilitating the production of products and provision of services that are useful – or comparatively more useful – to society, and instead may "actually encourage, rather than discourage, destructive activities". The number of
obese adults was approximately 600 million (12%) in 2015.
Environment

Many
environmentalists argue that GDP is a poor measure of social progress because it does not take into account harm to the
environment.
In the language of economics, everything comes down to its monetary value.
In essence, GDP rewards behaviors that are detrimental to the environment.
GDP also does not capture certain phenomena impacting citizens' well-being. For example, traffic jams could cause GDP to increase as there is a higher consumption of gasoline, however, GDP fails to consider citizens' well-being in terms of the quality of air due to air pollution from the traffic jams. Various alternatives have been developed(see below).
A 2020 study found that "poor regions' GDP grows faster by attracting more polluting
production after connection to China's expressway system. GDP may not be a tool capable of recognizing how much
natural capital agents of the economy are building or protecting.
In 2020 scientists, as part of a
World Scientists' Warning to Humanity-associated series, warned that worldwide growth in
affluence in terms of GDP-metrics has increased
resource use and
pollutant emissions with affluent
citizens of the world – in terms of e.g. resource-intensive consumption – being responsible for most negative environmental impacts and central to a transition to safer,
sustainable conditions. They summarised evidence, presented solution approaches and stated that far-reaching
lifestyle changes need to
complement technological advancements and that existing societies, economies and cultures
incite consumption expansion and that the
structural imperative for
growth in
competitive market economies inhibits
societal change.

in the long term, such as
deforestation, strip mining, overfishing and so on". The number of trees that are net lost annually is estimated to be approximately 10 billion. The global average annual deforested land in the 2015–2020 demi-decade was 10 million hectares and the average annual net forest area loss in the 2000–2010 decade 4.7 million hectares, according to the
Global Forest Resources Assessment 2020. According to one study, depending on the level of
wealth inequality, higher GDP-growth can be associated with more deforestation. In 2019 "agriculture and
agribusiness" accounted for 24% of the GDP of Brazil,
where a large share of annual net tropical forest loss occurred and is associated with sizable portions of this economic activity domain.
Steve Cohen of the Earth Institute elucidated that while GDP does not distinguish between different activities (or
lifestyles), "all consumption behaviors are not created equal and do not have the same impact on
environmental sustainability".

John B. Cobb and
Herman Daly introduced
Index of Sustainable Economic Welfare (ISEW) by taking into account other factors such as consumption of nonrenewable resources and degradation of the environment. ISEW is roughly defined as: personal consumption + public non-defensive expenditures − private defensive expenditures + capital formation + services from domestic labour − costs of
environmental degradation
Environment most often refers to:

− depreciation of natural capital.
In 2005,
Med Jones, an American Economist, at the International Institute of Management, introduced the first secular Gross National Happiness Index a.k.a.
Gross National Well-being framework and Index to complement GDP economics with additional seven dimensions, including environment, education, and government, work, social and health (mental and physical) indicators. The proposal was inspired by the King of Bhutan's
GNH philosophy.
In 2019, Serge Pierre Besanger published a "GDP 3.0" proposal which combines an expanded GNI formula which he calls GNIX, with a
Palma ratio and a set of environmental metrics based on the Daly Rule.
Standard of living
Although a high or rising level of GDP is often associated with increased economic and social progress, the opposite sometimes occurs. For example,
Jean Drèze and
Amartya Sen have pointed out that an increase in GDP or in GDP growth does not necessarily lead to a higher standard of living, particularly in areas such as healthcare and education. Another important area that does not necessarily improve along with GDP is political liberty, which is most notable in China, where GDP growth is strong yet political liberties are heavily restricted. GDP does not account for the distribution of income among the residents of a country, because GDP is merely an aggregate measure. An economy may be highly developed or growing rapidly, but also contain a wide gap between the rich and the poor in a society. These inequalities often occur on the lines of race, ethnicity, gender, religion, or other minority status within countries. This can lead to misleading characterizations of economic well-being if the

is heavily skewed toward the high end, as the poorer residents will not directly benefit from the overall level of wealth and income generated in their country (their purchasing power can decline, even as the mean
GDP per capita rises). GDP per capita measures (like aggregate GDP measures) do not account for income distribution (and tend to overstate the average income per capita). For example, South Africa during apartheid ranked high in terms of GDP per capita, but the benefits of this immense wealth and income were not shared equally among its citizens. The United Nations has aimed in its
Sustainable Development Goals
The ''2030 Agenda for Sustainable Development'', adopted by all United Nations (UN) members in 2015, created 17 world Sustainable Development Goals (SDGs). The aim of these global goals is "peace and prosperity for people and the planet" – wh ...
, amongst other global initiatives, to address wealth inequality.
GDP does not include several factors that influence the standard of living. In particular, it fails to account for:
*
Externalities – Economic growth may entail an increase in negative externalities that are not directly measured in GDP.
Increased industrial output might grow GDP, but any pollution is not counted.
* Non-market transactions – GDP excludes activities that are not provided through the market, such as household production, bartering of goods and services, and volunteer or unpaid services.
* Non-monetary economy – GDP omits economies where no money comes into play at all, resulting in inaccurate or abnormally low GDP figures. For example, in countries with major business transactions occurring informally, portions of local economy are not easily registered.
Bartering may be more prominent than the use of money, even extending to services.
* Quality improvements and inclusion of new products – by not fully adjusting for quality improvements and new products, GDP understates true
economic growth
In economics, economic growth is an increase in the quantity and quality of the economic goods and Service (economics), services that a society Production (economics), produces. It can be measured as the increase in the inflation-adjusted Outp ...
. For instance, although computers today are less expensive and more powerful than computers from the past, GDP treats them as the same products by only accounting for their monetary value. The introduction of new products is also difficult to measure accurately and is not reflected in GDP although it may increase the standard of living. For example, even the richest person in 1900 could not purchase standard products, such as antibiotics and cell phones, that an average consumer can buy today, since such modern conveniences did not exist then.
* Sustainability of growth – GDP is a measurement of economic historic activity and is not necessarily a projection.

– GDP does not account for variances in incomes of various demographic groups. See
income inequality metrics for discussion of a variety of inequality-based economic measures.
Proposals to overcome GDP limitations
In response to these and other limitations of using GDP, alternative approaches have emerged.
* In the 1980s,
Amartya Sen and
Martha Nussbaum developed the
capability approach, which focuses on the functional capabilities enjoyed by people within a country, rather than the aggregate wealth held within a country. These capabilities consist of the functions that a person is able to achieve.
* In 1990,
Mahbub ul Haq, a Pakistani economist at the United Nations, introduced the
Human Development Index
The Human Development Index (HDI) is a statistical composite index of life expectancy, Education Index, education (mean years of schooling completed and expected years of schooling upon entering the education system), and per capita income i ...
(HDI). The HDI is a composite index of life expectancy at birth, adult literacy rate and standard of living measured as a logarithmic function of GDP, adjusted to purchasing power parity.

European Union

released a communication titled ''GDP and beyond: Measuring progress in a changing world''
that identified five actions to improve indicators of progress in ways that make them more responsive to the concerns of its citizens.
* In 2009 Professors
Joseph Stiglitz,
Amartya Sen, and
Jean-Paul Fitoussi at the
Commission on the Measurement of Economic Performance and Social Progress (CMEPSP), formed by French President,
Nicolas Sarkozy published a proposal to overcome the limitation of GDP economics to expand the focus to well-being economics with a well-being framework consisting of health, environment, work, physical safety, economic safety, and political freedom. This has been adopted in a number of countries as a
wellbeing economy policy.
* In 2008, the
Centre for Bhutan Studies began publishing the
Bhutan Gross National Happiness (GNH) Index, whose contributors to happiness include physical, mental, and spiritual health; time balance; social and community vitality; cultural vitality; education; living standards; good governance; and ecological vitality.
* In 2013, the
OECD Better Life Index was published by the OECD. The dimensions of the index included health, economic, workplace, income, jobs, housing, civic engagement, and
life satisfaction
Life satisfaction is an evaluation of a person's quality of life. It is assessed in terms of mood, relationship satisfaction, achieved goals, self-concepts, and the self-perceived ability to cope with life. Life satisfaction involves a favorabl ...
.
* Since 2012, John Helliwell,
Richard Layard and
Jeffrey Sachs have edited an annual
World Happiness Report which reports a national measure of subjective well-being, derived from a single survey question on satisfaction with life. GDP explains some of the cross-national variation in life satisfaction, but more of it is explained by other, social variables (See 2013 World Happiness Report).
* In 2019, Erik Brynjolfsson and Avinash Collis argued that GDP does not reflect the growing value of many digital goods because they have zero price. Along with several coauthors, they proposed an alternative approach
GDP-B which is based on measuring the ''benefits'' of goods and services, rather than their price or cost.
* At the beginning of the 21st century the World Economic Forum published a series of analyses and propositions to create economic measurement tools more effective than GDP.
* China launched the
Gross Ecosystem Product (GEP) in 2020. It measures the contribution of ecosystems to the economy, including by regulating climate. It spread widely across the country. The first province to issue local rules about GEP was
Zhejiang , and a year later it has already decided the fate of a project in the
Deqing region. For example, the GEP of Chengtian Radon Spring Nature Reserve has been calculated as US$43 million.
Problems with GDP data
A peer-reviewed study published in the ''
Journal of Political Economy'' in October 2022 found signs of manipulation of

statistics in the majority of countries. According to the study, this mainly applied to countries that were governed semi-authoritarian/authoritarian or did not have a functioning
separation of powers. The study took the annual growth in the brightness of lights at night, as measured by satellites, and compared it to officially reported economic growth. Authoritarian states had consistently higher reported growth in GDP than their growth in night lights would suggest. An effect that also cannot be explained by different economic structures, sector composition or other factors. Incorrect growth statistics can also falsify indicators such as GDP or GDP per capita.
