In 1938, the year before the Second World War, the United States had, by far, the largest economy in the world in terms of gross domestic product (GDP). The five Allied Great Powers that emerged victorious from the war, along with the three Axis Tripartite Pact countries that were ultimately defeated made up the eight largest independent economies in 1938.

When values are converted into 1990 international dollars, the U.S. GDP was over 800 billion dollars in 1938, which was more than double that of the second largest economy, the Soviet Union. Even the combined economies of the UK, its dominions, and colonies had a value of just over 680 billion 1990 dollars, showing that the United States had established itself as the world's leading economy during the interwar period (despite the Great Depression).

Interestingly, the British and Dutch colonies had larger combined GDPs than their respective metropoles, which was a key motivator for the Japanese invasion of these territories in East Asia during the war. Trade with neutral and non-belligerent countries also contributed greatly to the economic development of Allied and Axis powers throughout the war; for example, natural resources from Latin America were essential to the American war effort, while German manufacturing was often dependent on Swedish iron supplies.

In 2024, the U.S. GDP increased from the previous year to about 29.18 trillion U.S. dollars. Gross domestic product (GDP) refers to the market value of all goods and services produced within a country. In 2024, the United States has the largest economy in the world. What is GDP? Gross domestic product is one of the most important indicators used to analyze the health of an economy. GDP is defined by the BEA as the market value of goods and services produced by labor and property in the United States, regardless of nationality. It is the primary measure of U.S. production. The OECD defines GDP as an aggregate measure of production equal to the sum of the gross values added of all resident, institutional units engaged in production (plus any taxes, and minus any subsidies, on products not included in the value of their outputs). GDP and national debt Although the United States had the highest Gross Domestic Product (GDP) in the world in 2022, this does not tell us much about the quality of life in any given country. GDP per capita at purchasing power parity (PPP) is an economic measurement that is thought to be a better method for comparing living standards across countries because it accounts for domestic inflation and variations in the cost of living. While the United States might have the largest economy, the country that ranked highest in terms of GDP at PPP was Luxembourg, amounting to around 141,333 international dollars per capita. Singapore, Ireland, and Qatar also ranked highly on the GDP PPP list, and the United States ranked 9th in 2022.

On October 29, 1929, the U.S. experienced the most devastating stock market crash in it's history. The Wall Street Crash of 1929 set in motion the Great Depression, which lasted for twelve years and affected virtually all industrialized countries. In the United States, GDP fell to it's lowest recorded level of just 57 billion U.S dollars in 1933, before rising again shortly before the Second World War. After the war, GDP fluctuated, but it increased gradually until the Great Recession in 2008. Real GDP Real GDP allows us to compare GDP over time, by adjusting all figures for inflation. In this case, all numbers have been adjusted to the value of the US dollar in FY2012. While GDP rose every year between 1946 and 2008, when this is adjusted for inflation it can see that the real GDP dropped at least once in every decade except the 1960s and 2010s. The Great Recession Apart from the Great Depression, and immediately after WWII, there have been two times where both GDP and real GDP dropped together. The first was during the Great Recession, which lasted from December 2007 until June 2009 in the US, although its impact was felt for years after this. After the collapse of the financial sector in the US, the government famously bailed out some of the country's largest banking and lending institutions. Since recovery began in late 2009, US GDP has grown year-on-year, and reached 21.4 trillion dollars in 2019. The coronavirus pandemic and the associated lockdowns then saw GDP fall again, for the first time in a decade. As economic recovery from the pandemic has been compounded by supply chain issues, inflation, and rising global geopolitical instability, it remains to be seen what the future holds for the U.S. economy.

In the build up to the Second World War, the United States was the major power with the highest gross domestic product (GDP) per capita in the world. In 1938, the United States also had the highest overall GDP in the world, and by a significant margin, however differences in GDP per person were much smaller. Switzerland In terms of countries that played a notable economic role in the war, the neutral country of Switzerland had the highest GDP per capita in the world. A large part of this was due to the strength of Switzerland's financial system. Most major currencies abandoned the gold standard early in the Great Depression, however the Swiss Franc remained tied to it until late 1936. This meant that it was the most stable, freely convertible currency available as the world recovered from the Depression, and other major powers of the time sold large amounts of gold to Swiss banks in order to trade internationally. Switzerland was eventually surrounded on all sides by Axis territories and lived under the constant threat of invasion in the war's early years, however Swiss strategic military planning and economic leverage made an invasion potentially more expensive than it was worth. Switzerland maintained its neutrality throughout the war, trading with both sides, although its financial involvement in the Holocaust remains a point of controversy. Why look at GDP per capita? While overall GDP is a stronger indicator of a state's ability to fund its war effort, GDP per capita is more useful in giving context to a country's economic power in relation to its size and providing an insight into living standards and wealth distribution across societies. For example, Germany and the USSR had fairly similar GDPs in 1938, whereas Germany's per capita GDP was more than double that of the Soviet Union. Germany was much more industrialized and technologically advanced than the USSR, and its citizens generally had a greater quality of life. However these factors did not guarantee victory - the fact that the Soviet Union could better withstand the war of attrition and call upon its larger population to replenish its forces greatly contributed to its eventual victory over Germany in 1945.

The Covid-19 pandemic saw growth fall by 2.2 percent, compared with an increase of 2.5 percent the year before. The last time the real GDP growth rates fell by a similar level was during the Great Recession in 2009, and the only other time since the Second World War where real GDP fell by more than one percent was in the early 1980s recession. The given records began following the Wall Street Crash in 1929, and GDP growth fluctuated greatly between the Great Depression and the 1950s, before growth became more consistent.

Between 1900 and 1950, Scandinavian countries saw the largest growth in GDP per capita in Europe, more than doubling between 1913 and 1950. In comparison, growth rates were much lower in Western Europe, and lower still in East-Central Europe. From 1913 (the year before the First World War) until the end of the Second World War's recovery period in 1950, Western Europe's GDP per capita grew by just 43 percent, while East-Central Europe's figure increased by just 26 percent.

At the turn of the 20th century, industrialization in Western Europe and North America saw new countries emerge (or return) as major economic powers. Germany (established in 1871) and the United States were the two countries that began to challenge the established powers such as Britain and the Netherlands on an industrial scale, while France's invigorated banking system compensated for its slow rate of industrialization. This period also saw Scandinavian countries catch up with modernization rates observed in other Western European countries; the wealth of natural resources, increased industrial output, and strong shipping networks combined to allow GDP per capita to grow at rates similar to the United States and France and Germany.

Between 1970 and 1913, GDP per capita in the three emerging regions roughly doubled, outpacing growth in countries considered economic and industrial "leaders" for most of the 1800s. While Britain had been the leading global superpower for most of the 19th century and still maintained healthy economic growth in the given period, the rise of Germany and the U.S. at this time would (and, later, the Soviet Union) go on to shape global economic development over the subsequent decades.

Throughout the first half of the twentieth century, GDP per capita rose significantly across Europe, however, at varying rates across different regions. Scandinavia, which did not experience the same level of structural devastation during the World Wars as the other regions, saw the largest GDP per capita growth during this period. Over these five decades, Scandinavian countries transformed from traditional agricultural societies to some of the world's wealthiest and industrially advanced economies. Between 1913 and 1950, Scandinavian GDP per capita doubled, eventually overtaking Western Europe as the highest in Europe. In comparison, East-Central Europe's growth was much slower, rising by just 26 percent between 1913 and 1915.

Government spending in the United Kingdom was approximately 44.7 percent of GDP in 2024/25, compared with 39.6 percent in 2019/20.

The United Kingdom's economy grew by 1.1 percent in 2024, after a growth rate of 0.3 percent in 2023, 5.1 percent in 2022, 8.5 percent in 2021, and a record ten percent fall in 2020. During the provided time period, the biggest annual fall in gross domestic product before 2020 occurred in 2009, when the UK economy contracted by 4.6 percent at the height of the global financial crisis of the late 2000s. Before 2021, the year with the highest annual GDP growth rate was 1973, when the UK economy grew by 6.5 percent. UK economy growing but GDP per capita falling In 2022, the UK's GDP per capita amounted to approximately 37,371 pounds, with this falling to 37,028 pounds in 2023, and 36,977 pounds in 2024. While the UK economy as a whole grew during this time, the UK's population grew at a faster rate, resulting in the negative growth in GDP per capita. This suggests the UK economy's struggles with productivity are not only stagnating, but getting worse. The relatively poor economic performance of the UK in recent years has not gone unnoticed by the electorate, with the economy consistently seen as the most important issue for voters since 2022. Recent shocks to UK economy In the second quarter of 2020, the UK economy shrank by a record 20.3 percent at the height of the COVID-19 pandemic. Although there was a relatively swift economic recovery initially, the economy has struggled to grow much beyond its pre-pandemic size, and was only around 3.1 percent larger in December 2024, when compared with December 2019. Although the labor market has generally been quite resilient during this time, a long twenty-month period between 2021 and 2023 saw prices rise faster than wages, and inflation surge to a high of 11.1 percent in October 2022.

From 1820 to 1913, the global GDP almost quadrupled, from just under 700 billion FY1990 U.S. dollars to more than 2.7 trillion FY1990 USD. As Europe industrialized throughout this period, its share of the global GDP increased from roughly one-third in 1820 to 46 percent in 1913, with Western European* countries disproportionately driving this growth. However, the combined growth of North America, Australia, and New Zealand saw the most significant development over this period, rising from 14 billion FY1990 USD in 1820 to 583 billion FY1990 USD in 1913. While the Asia-Pacific region had the largest share of global GDP in 1820, the slower rate of industrialization meant that its share dropped significantly by 1913. This region saw the lowest growth rate during this period.

The government of the United Kingdom borrowed approximately 2.6 percent worth of its GDP in the 2024/25 financial year, compared with 2.3 percent in 2023/24. In 2020/21, government borrowing reached 11.6 percent of GDP, due to increased financial support to public services during the COVID-19 pandemic, combined with reduced revenue because of societal lockdowns.

In 1900, GDP per capita in Southern Europe was just over half of the rate in Western Europe, while it was just 39 percent across Central and Eastern Europe. By 1950, Central and Eastern Europe's GDP per capita had risen to 51 percent of Western Europe's, while Southern Europe's GDP per capita had fallen to 44 percent. Post-war recovery across the south was comparatively slower than the West due to the lack of American investment in the fascist states of Spain and Portugal, the civil war in Greece, and the lack of industrialization in Italy. As these factors reversed or concluded in the 1950s, Southern Europe's economic development fell more in line with that of the rest of Western Europe in this decade, with Italy, in particular, emerging as one of the world's leading economies.

Throughout the early 20th century, Italy consistently had the highest GDP per capita in Southern Europe, which grew consistently at each given interval. Portugal was the only other country to see consistent growth between the four given years, whereas the civil wars in Spain (1936-1939) and Greece (1946-1949) saw their respective GDP per capita fall in the corresponding years. Overall, GDP per capita across these four countries grew by just 28 percent between 1913 and 1950, although it did drop in 1938 due to the Spanish Civil War. Southern Europe's GDP per capita in 1950 was just 51 percent of the rate in Western Europe.

Public sector net debt amounted to 93.5 percent of gross domestic product in the United Kingdom during the 2024/25 financial year. Following the COVID-19 pandemic, UK government debt has reached levels not seen since the early 1960s, due to a significant increase in borrowing in 2020/21. After peaking at 251.7 percent shortly after the end of the Second World War, government debt in the UK gradually fell, before a sharp increase in the late 2000s at the time of the global financial crisis. Debt not expected to start falling until 2029/30 In 2024/25, the UK's government expenditure was approximately 1.28 trillion pounds, around 44 percent of GDP. This spending was financed by 1.14 trillion pounds of revenue raised, and almost 150 billion pounds of borrowing. Although the UK government can continue to borrow money to finance its spending, the amount spent on debt interest has increased significantly in recent years. Current forecasts suggest that while the debt is eventually expected to start declining, this is based on falling government deficits in the next five years. Government facing hard choices Hitting fiscal targets, such as reducing the national debt, will require a careful balancing of the books from the current government, and the possibility for either spending cuts or tax rises. Although Labour ruled out raising the main government tax sources, Income Tax, National Insurance, and VAT, at the 2024 election, they did raise National Insurance for employers (rather than employees) and also cut Winter Fuel allowances for large numbers of pensioners. Less than a year after implementing cuts to Winter Fuel, the government performed a U-Turn on the issue, and also held back on more significant cuts to welfare.

In September 2024, the national debt of the United States had risen up to 35.46 trillion U.S. dollars. The national debt per capita had risen to 85,552 U.S. dollars in 2021. As represented by the statistic above, the public debt of the United States has been continuously rising. U.S. public debt Public debt, also known as national and governmental debt, is the debt owed by a nations’ central government. In the case of the U.S., national debt is owed by the federal government to Treasury security holders. Generally speaking, government debt increases with government spending, and can be decreased through taxes. During the COVID-19 pandemic, the U.S. government increased spending significantly to finance virus infrastructure, aid, and various forms of economic relief. International public debt Venezuela leads the global ranking of the 20 countries with the highest public debt in 2021. In relation to the Gross Domestic Product (GDP), Venezuela's public debt amounted to around 306.95 percent of GDP. Eritrea was ranked fifth, with an estimated debt of 170 percent of the Gross Domestic Product. The national debt of the United Kingdom is forecasted to grow from 87 percent in 2022 to 70 percent in 2027, in relation to the Gross Domestic Product. These figures include England, Wales, Scotland as well as Northern Ireland. Greece had the highest national debt among EU countries as of the 4th quarter of 2020 in relation to the Gross Domestic Product. Germany ranked 13th in the EU, with its national debt amounting to 69 percent of GDP in the same time period. Tuvalu was one of the 20 countries with the lowest national debt in 2021 in relation to the GDP, while Macao had an estimated level of national debt of zero percent, the lowest of any country. The data refer to the debts of the entire state, including the central government, the provinces, municipalities, local authorities and social insurance.
