What is gross domestic product (GDP)?
Gross Domestic Product (GDP) is the most widely-recognised way to measure the economic performance of a country. It is extensively relied upon by analysts, investors, industry professionals, and policymakers.
QUOTE
"Improving the quality of our lives should be the ultimate target of public policies. But public policies can only deliver the best fruit if they are based on reliable tools to measure the improvement they seek to produce in our lives."
However, while it is a key metric, GDP alone does not indicate long-term stability or the quality of life for families and individuals in a specific country. Policymakers and leading economists like Angela Merkel, David Cameron, and Joseph Stiglitz have stated that alternative measures are needed to move forward in the 21st century.
After all, a higher average GDP per capita may not mean equally and evenly distributed resources across a given country.

Big ideas
- The GDP is one of the primary formulas that demonstrates the economic health of a country. It indicates size and growth rate.
- There are three primary types of GDP - Real GDP, Nominal GDP, and GDP per capita. There are three formulas to measure GDP, but all should generate the same result.
- GDP is relied on extensively by policymakers and investors for informed decision-making. But it has certain limitations and it might be time to expand it to take mental health, as well as social welfare, into account.
A definition and explanation of GDP - what does gross domestic product measure?
The GDP of a country is calculated annually (year-over-year), though sometimes it can be calculated for a given quarter (quarter-over-quarter). It can also be adjusted for inflation to generate a more accurate picture of economic conditions. This is called real GDP. More than perhaps any other formula, the GDP indicates how well a country is doing economically.
There are three primary types of GDP that can be analyzed. Real GDP takes inflation into account while Nominal GDP does not. So Real GDP is a little more accurate than nominal GDP because inflation plays an important role in the spending power of money. GDP per Capita is also very important because it indicates the economic output per person living in the country.
There are three ways to measure GDP:

Alongside the total GDP, the GDP growth rate can also be taken into account to see how fast a country is growing.
In sum, the GDP is useful to determine the economic health of a country and the standard of living for each citizen as adjusted for inflation. These are key metrics, and this is why GDP is a good indicator for comparing the economic well-being of various countries.

The formula for gross domestic product
There are three primary GDP formulas. All of these formulas should generate the same result if they are calculated correctly. The three formulas are the Expenditure Approach, Income Approach, and Production Approach.
The Expenditure Approach adds up all the expenditures on goods and services within a country during a specific time period. This includes consumption spending by households (C), investment spending by businesses (I), government spending on goods and services (G), imports (M), and exports(X).
The Expenditure Approach adds up all the expenditures on goods and services within a country during a specific time period. This includes consumption spending by households (C), investment spending by businesses (I), government spending on goods and services (G), imports (M), and exports(X).
FORMULA
GDP = C + I + G + (X - M)
The Income Approach adds up all the income earned by households and businesses within a country during a specific time period. This includes wages, salaries, profits, and rental income.
FORMULA
GDP = Compensation of employees + Gross operating surplus + Taxes on production and imports - Subsidies + Net property income + Consumption of fixed capital
The Production Approach is the most simple. This approach adds up the value of all goods and services produced within a country during a specific time period.
FORMULA
GDP = Value of output - Value of Intermediate Consumption
The three primary types of GDP include the Real GDP, Nominal GDP, and GDP per capita:
Real GDP
Real GDP is derived from nominal GDP and adjusted for inflation. Real GDP is more accurate because rising inflation will push up nominal GDP without any material value to the economy (and potentially to the detriment of the economy). Real GDP is calculated by using a base year as a reference where the price of goods is constant.
Nominal GDP
Nominal GDP is the total GDP without any adjustment for inflation. It is often used when comparing two quarters. For annual measurements, Real GDP is preferable. Nominal GDP can be evaluated in either local currency or US dollars.
GDP per capita
This measure provides an indication of the average economic well-being of individuals in a country. GDP per capita is often used as a standard measure of economic development and is useful for comparing the economic performance of different countries. It takes into account differences in population size and provides a more accurate picture of a country's economic performance than total GDP alone.
Higher GDP per capita generally indicates that the average individual in a country has a higher standard of living and more resources available to them. However, it's important to note that GDP per capita does not account for income inequality or variations in the distribution of wealth within a country.
Types of gross domestic product: GDP growth rate
Additional types of GDP include the GDP growth rate and the Purchasing Power Parity (PPP). The GDP growth rate is a measure of the change in a country's GDP over a certain period of time, typically a year or a quarter. It measures the rate of expansion or contraction of a country's economy over a specific period and is expressed as a percentage.
The GDP growth rate is calculated by taking the difference between the current GDP and the previous year’s (or quarter’s) GDP and then dividing that difference by the previous GDP. The resulting figure is then multiplied by 100 to generate a percentage.

FORMULA
GDP Growth Rate = GDP / Size of Population
High GDP growth rates are generally associated with positive economic conditions such as increased employment opportunities, higher wages, and improved standards of living. Conversely, low or negative GDP growth rates can lead to economic stagnation, job losses, and a decline in living standards.
Types of gross domestic product: GDP purchasing power parity
GDP Purchasing Power Parity (PPP) is a measure of the relative value of different currencies based on the concept of "purchasing power". It measures differences in prices between countries to arrive at the total GDP.
When calculating GDP using PPP, a common set of prices for a basket of goods and services is used across countries to determine the real value of goods and services produced. This method adjusts for the differences in prices between countries, which can distort comparisons of economic output based on market exchange rates.

Source: WikipediaFor example, a country with a weak currency may have a lower GDP than a country with a stronger currency, even if the actual production of goods and services is similar. This is because the weak currency may make goods and services cheaper in international markets, and therefore, the country's GDP would appear lower when converted into a stronger currency.
GDP PPP is used as a standard measure of economic development and is often used to compare the economic performance of different countries. It provides a more accurate picture of the relative size and growth of different economies, as it takes into account differences in the cost of living across countries.

Why gross domestic product is important
The Gross Domestic Product (GDP) is an indicator that has been relied upon throughout the 20th century. It is important for several reasons:
- Measuring economic growth - GDP is a commonly used measure of economic growth and provides an indication of the size and health of a country's economy over time. It is often used to compare the economic performance of different countries.
- Government policy - GDP is used by governments to guide economic policy decisions. A high GDP can provide governments with more resources to invest in public goods and services, including education and healthcare. Governments may also use GDP to determine tax policy, monetary policy, and fiscal policy.
- Business planning - A strong GDP may indicate a favourable business climate, leading to increased investment and expansion opportunities. It can be relied upon to make investment decisions in line with wider economic data as well as industry-specific information.
- Employment - GDP is closely related to employment levels. A growing GDP may lead to increased job opportunities and a reduction in unemployment rates.
- Standard of living - GDP can indicate the standard of living within a country. A high GDP can translate into higher incomes, increased access to public goods and services, and improved quality of life for individuals.
While GDP is an important measure of economic activity, it's important to note that it doesn't capture all aspects of well-being and can't account for factors such as income distribution, environmental sustainability, and social well-being. Thus, it's important to use other measures in conjunction with GDP to gain a more comprehensive understanding of economic and social well-being.
Many policymakers have suggested that we need to measure other variables on top of the GDP to calculate overall quality of life and that perhaps existing GDP measures need to be upgraded.

"The appropriate choice of indicators is key to boost our understanding of the complexity of our diverse societies within the European Union, to better communicate on it, and to better respond to new policy needs as, for example, with the "GDP and beyond" initiative to include measurement of well-being."
Gross domestic product of UK
The gross domestic product in the UK is quite high by global standards. According to the World Bank, the Gross Domestic Product of the UK was approximately 2.74 trillion US dollars in 2020.
The UK is the sixth-largest economy in the world by nominal GDP, and it has a highly developed service-based economy. The UK has a diverse range of industries, including financial services, manufacturing, healthcare, and technology, among others.
The gross domestic product in the UK has some facts that separate it from other developed nations. Over 80% of the gross domestic product in the UK is derived from the services industry, though it has significant manufacturing and agricultural output.

GDP: UK vs Germany vs France
While its GDP grew at a 1.7% annual rate in 2019, it contracted by 9.8% in 2020 due to the impact of the pandemic. However, it should be borne in mind that the GDP is not even across different geographic locations. London and the southeast have the highest GDP per capita, while some areas of the north and west have a lower GDP per capita.
Despite much hype and hysteria, breaking away from Europe does not seem to have had major consequences for the gross domestic product in the UK. Its GDP rose by 15% in 2021. GDP per capita and GDP growth rate also rose considerably.

GDP across the globe
In terms of GDP, some countries certainly do better than others. Even if money is not a determinant of happiness beyond a certain point, there is a reason why immigrants flee poorer regions towards more affluent first-world nations with superior standards of living.
GDP per capita is a good indication of the quality of life, even if it does not outline the entire situation. Countries with higher GDP per capita are often regarded as having a better standard of living (USA, UK, Germany, Canada, etc.)
While countries such as India and China have a higher overall GDP, their GDP per capita signals an inferior standard of living. The chart below, based on World Bank information, shows the global GDP distribution. The biggest countries have a disproportionate share of global GDP production.

This, along with historical factors, is a prime reason why some countries have such impressive GDP in comparison to other regions of the globe.
Recap
Gross Domestic Product and its different types (nominal, real, per capita, growth, PPP) have been the main formulas used to measure the economic well-being of a country. It is still relied upon by most analysts, policymakers, businesses, and investors. It is incredibly useful.
However, it is still not a full measurement of the quality of life of an individual or household, and many policymakers and economists have stated the need for a more accurate and holistic measurement to determine overall satisfaction levels for individuals within a given country.

FAQ
Q: What is a simple definition of GDP?
GDP stands for Gross Domestic Product, which is the total value of all goods and services produced within a country's borders during a specific period, typically a year. It is a measure of the size and growth of a country's economy.
GDP includes all final goods and services produced, regardless of who produces them. It’s usually calculated by adding up the value of all goods and services produced minus the net of intermediate consumption within a country during a specific time period.
It is a key indicator of a country's economic health and is often used to compare the relative economic performance of different countries.

Q: How is GDP calculated?
There are three primary ways to calculate GDP: expenditure, income, and production. The production approach is the most straightforward, though each approach should give the same result if correctly calculated.
The production approach is: GDP = Value of Output - Value of intermediate consumption. The value of output is the value of the entirety of goods/services produced in a year. Intermediate consumption relates to the values of goods and services of production but not the end commercial product.
The production approach is: GDP = Value of Output - Value of intermediate consumption. The value of output is the value of the entirety of goods/services produced in a year. Intermediate consumption relates to the values of goods and services of production but not the end commercial product.
Q: Who benefits from a high GDP?
Everybody, in theory. A high GDP often translates into higher incomes, increased employment opportunities, and a higher standard of living for individuals. This can lead to better access to healthcare, education, and other basic necessities and an improved quality of life. The strong economy benefits businesses, which will have increased demand for their products and services. It offers a favorable investment climate for investors, and governments have more revenue for their projects.
However, it's up for debate whether or not this will benefit everybody in the same manner. Within many societies, wealth is polarized at the top, and it does not always trickle down, at least not evenly. This is a major disadvantage of the GDP.
Additionally, a focus solely on GDP growth may not account for other important factors such as income distribution, environmental sustainability, and social well-being.

Q: What are the 5 components of GDP?
The five components of GDP are: personal consumption expenditures (C), gross private domestic investment (I), government consumption expenditures and gross investment (G), Net Exports of Goods and Services (X - M), and other factors (depreciation, subsidies, indirect taxes).
Other factors refer to additional factors that can impact GDP. Depreciation represents the decrease in the value of capital goods over time. Subsidies are payments made by the government to businesses or individuals to encourage certain economic activities. Indirect taxes are taxes on goods and services that are included in the price and paid by the consumer (such as sales taxes).

Q: Which country has the strongest economy in Europe?
As of 2021, the country with the strongest GDP in Europe is Germany. According to the International Monetary Fund (IMF), Germany's GDP in 2021 was estimated to be over $4 trillion, making it the fourth-largest economy in the world after the United States, China, and Japan. Germany has a highly developed economy and is a global leader in manufacturing, technology, and engineering. Other countries in Europe with strong GDPs include the United Kingdom, France, Italy, and Spain.
- Inflation: A general increase in prices for goods and services, which reduces how much a single unit of currency can buy over time.
- Fiscal Policy: The way governments adjust tax rates and public spending to influence economic activity, aiming to affect employment, consumption, and growth.
- Monetary Policy: Central banks’ use of tools like setting interest rates or modifying the money supply to steer economic conditions and maintain stability.
- Income Inequality: The uneven distribution of earnings among different individuals or groups within a society, highlighting gaps between the richest and poorest.
- Quality of Life: A broad measure of overall well-being, considering factors such as health, education, personal security, and environmental conditions.
