Economy & Politics

In 2025, Liechtenstein had the highest gross domestic product per capita in the world at just over 231,700 U.S. dollars. The top five largest economies in terms of GDP per capita were all in Europe, with the Singapore having the largest GDP per capita in the rest of the world. The United States had the largest GDP per capita among American countries, while Qatar had the largest GDP per capita in the Middle East. 

While GDP is a useful indicator for measuring the size or strength of an economy, GDP per capita is much more reflective of living standards. For example, when compared to life expectancy or indices such as the Human Development Index or the World Happiness Report, there is a strong overlap - 14 of the 20 countries on this list are also ranked among the 20 happiest countries in 2024, and all 20 have "very high" HDIs.

GDP per capita figures, however, can be misleading, and to paint a fuller picture of a country's living standards then one must look at multiple metrics. GDP per capita figures can be skewed by inequalities in wealth distribution, and in countries such as those in the Middle East, a relatively large share of the population lives in poverty while a smaller number live affluent lifestyles. 

As of March 2025, South Africa had the highest unemployment rate among the 19* countries that are members of the G20. The unemployment rate in South Africa stood at 33.9 percent that year. The country has recently been plagued by an economic downturn, including energy shortages and high unemployment levels. On the other hand, Japan had the lowest unemployment rate at just 2.5 percent.

Not only does South Africa top the G20 in overall unemployment, but it also has a significant level of youth unemployment, as nearly half of the young population is unemployed. Thirty years after the end of Apartheid, South Africa is also still one of the most unequal countries in the world, with a Gini score of 0.63. The prominence of inequality in the country makes escaping unemployment and underemployment difficult.

While Japan had the lowest unemployment rate out of all G20 nations, as well as the lowest youth unemployment rate out of the G20 nations, Japan’s economy is still facing many challenges. With an aging population, the total Japanese population is facing a rapid decline, meaning that it will struggle to have enough workers participating in the labor market. Despite this, Japan maintains strict immigration policies, limiting the chances for foreign workers to move to Japan. Moreover, Japan has the second lowest fertility rate out of the G7 nations and one of the lowest fertility rates globally, adding another challenge in addressing population shrinkage.

At 7.99 U.S. dollars, Switzerland has the most expensive Big Macs in the world, according to the January 2025 Big Mac index. Concurrently, the cost of a Big Mac was 5.79 dollars in the U.S., and 5.95 U.S. dollars in the Euro area. 

The Big Mac index, published by The Economist, is a novel way of measuring whether the market exchange rates for different countries’ currencies are overvalued or undervalued. It does this by measuring each currency against a common standard – the Big Mac hamburger sold by McDonald’s restaurants all over the world. Twice a year the Economist converts the average national price of a Big Mac into U.S. dollars using the exchange rate at that point in time. As a Big Mac is a completely standardized product across the world, the argument goes that it should have the same relative cost in every country. Differences in the cost of a Big Mac expressed as U.S. dollars therefore reflect differences in the purchasing power of each currency.

Purchasing power parity (PPP) is the idea that items should cost the same in different countries, based on the exchange rate at that time. This relationship does not hold in practice. Factors like tax rates, wage regulations, whether components need to be imported, and the level of market competition all contribute to price variations between countries. The Big Mac index does measure this basic point – that one U.S. dollar can buy more in some countries than others. There are more accurate ways to measure differences in PPP though, which convert a larger range of products into their dollar price. Adjusting for PPP can have a massive effect on how we understand a country’s economy. The country with the largest GDP adjusted for PPP is China, but when looking at the unadjusted GDP of different countries, the U.S. has the largest economy.

The United States led the ranking of the countries with the highest military spending in 2024, with 997 billion U.S. dollars dedicated to the military. That constituted almost 40 percent of the total military spending worldwide that year, which amounted to 2.7 trillion U.S. dollars. This amounted to 3.4 percent of the U.S.'s gross domestic product (GDP), placing the country lower in the ranking of military expenditure as a percentage of GDP, compared to Ukraine, Israel, Algeria, Saudi Arabia, and Russia. China was the second largest military spender, with an estimated 314 billion U.S. dollars spent, with Russia following in third. 

Defense budget

According to the U.S. Congressional Budget Office, the outlays for defense will rise to 1.1 trillion U.S. dollars by 2033. The largest parts of the budget are dedicated to the Departments of the Navy and the Air Force. The budget for the U.S. Air Force for 2024 was nearly 260 billion U.S. dollars.

Global military spending

The value of military spending globally has grown steadily in the past years and reached 2.7 trillion U.S. dollars in 2024. Reasons for this are the outbreak of the Russia-Ukraine war in 2022, the war in Gaza, as well as increasing tensions in the South China Sea. North America is by far the leading region worldwide in terms of expenditure on the military.

In August 2025, the public debt of the United States was around 37.27 trillion U.S. dollars, a slight decrease from the previous month. The U.S. public debt ceiling has become one of the most prominent political issues in the States in recent years, with debate over how to handle it causing political turmoil between Democrats and Republicans.

The public debt of the United States has risen quickly since 2000, and in 2022 was more than five times higher than in 2000. The public debt is the total outstanding debt that is owed by the federal government. This figure comprises debt owed to the public (for example, through bonds) and intergovernmental debt (debt owed to various governmental departments), such as Social Security.

The debt issue has become a highly contentious topic within the U.S. government. Measures such as stimulus packages, social programs and tax cuts add to the public debt. Additionally, spending tends to peak during large global events, such as the Great Depression, the 2008 financial crisis, or the COVID-19 pandemic - all of which had a detrimental impact on the U.S. economy. Although both major political parties in the U.S. tend to blame one another for increases in the country's debt, a recent analysis found that both parties have contributed almost equally to national expenditure.

Debate on raising the debt ceiling, or the amount of debt the federal government is allowed to have at any one time, was a leading topic in the government shutdown in October 2013. Despite plans from both Democrats and Republicans on how to lower the national debt, it is only expected to increase over the next decade.

In 2025, the United States had the largest number of active military personnel out of all North Atlantic Treaty Organization (NATO) countries, with almost 1.3 million troops. The country with the second-largest number of military personnel was Türkiye, at around 355,200 active personnel. Additionally, the U.S. has by far the most armored vehicles in NATO, as well as the largest Navy and Air Force. 

NATO in brief

NATO, which was formed in 1949, is the most powerful military alliance in the world. At its formation, NATO began with 12 member countries, which by 2024 had increased to 32. NATO was originally formed to deter Soviet expansion into Europe, with member countries expected to come to each other’s defense in case of an attack. Member countries are also obliged to commit to spending two percent of their respective GDPs on defense, although many states have recently fallen far short of this target. 

NATO in the contemporary world

Some questioned the purpose of NATO after the fall of the Berlin Wall in 1989 and the collapse of the Soviet Union a few years later. In 2019, French President Emmanuel Macron even called the organization 'brain-dead' amid dissatisfaction with the leadership of the U.S. President at the time, Donald Trump. NATO has, however, seen a revival after Russia's invasion of Ukraine in February 2022. Following the invasion, Sweden and Finland both abandoned decades of military neutrality and applied to join the alliance, with Finland joining in 2023 and Sweden in 2024.

According to the Hurun Global Rich List 2025, the United States housed the highest number of billionaires worldwide in 2025. In detail, there were 870 billionaires living in the United States as of January that year. By comparison, 823 billionaires resided in China. India, the United Kingdom, and Germany were also the homes of a significant number of billionaires that year.

As the founder and exporter of consumer capitalism, it is no surprise that the United States is home to a large number of billionaires. Although China had briefly overtaken the U.S. recently, the United States has reclaimed its position as the country with the most billionaires in the world. Moreover, North America leads the way in terms of the highest number of ultra high net worth individuals – those with a net worth of more than fifty million U.S. dollars. The prominence of Europe and North America is a reflection of the higher degree of economic development in those states. However, this may also change as China and other emerging economies continue developing.

Moreover, the small proportion of female billionaires does little to counter critics claiming the global economy is dominated by an elite comprised mainly of men. On the list of the richest people in the world, only two were women. Moreover, recent political discourse has put a great amount of attention on the wealth held by the super-rich, with the wealth distribution of the global population being heavily unequal.

In 2025, the United States government donated around 1.2 billion U.S. dollars in humanitarian aid worldwide. The European Commission and Germany followed with over 1.25 U.S. dollars. However, this only shows one part of the picture, as the largest economies are likely to be the largest donors. Another way of looking at the largest donors are by how much each country gave as a share of their gross domestic product.

Inflation is generally defined as the continued increase in the average prices of goods and services in a given region. Following the extremely high global inflation experienced in the 1980s and 1990s, global inflation has been relatively stable since the turn of the millennium, usually hovering between three and five percent per year. There was a sharp increase in 2008 due to the global financial crisis now known as the Great Recession, but inflation was fairly stable throughout the 2010s, before the current inflation crisis began in 2021.

Despite the economic impact of the coronavirus pandemic, the global inflation rate fell to 3.26 percent in the pandemic's first year, before rising to 4.66 percent in 2021. This increase came as the impact of supply chain delays began to take more of an effect on consumer prices, before the Russia-Ukraine war exacerbated this further. A series of compounding issues such as rising energy and food prices, fiscal instability in the wake of the pandemic, and consumer insecurity have created a new global recession, and global inflation in 2024 is estimated to have reached 5.76 percent. This is the highest annual increase in inflation since 1996. 

Venezuela is the country with the highest individual inflation rate in the world, forecast at around 200 percent in 2022. While this is figure is over 100 times larger than the global average in most years, it actually marks a decrease in Venezuela's inflation rate, which had peaked at over 65,000 percent in 2018. Between 2016 and 2021, Venezuela experienced hyperinflation due to the government's excessive spending and printing of money in an attempt to curve its already-high inflation rate, and the wave of migrants that left the country resulted in one of the largest refugee crises in recent years. In addition to its economic problems, political instability and foreign sanctions pose further long-term problems for Venezuela. While hyperinflation may be coming to an end, it remains to be seen how much of an impact this will have on the economy, how living standards will change, and how many refugees may return in the coming years.
