A country of farmers became a quarter of the world economy
In the early 1800s, over four in five Americans worked the land. Today the United States produces about 26 percent of global output, the most of any nation measured at market exchange rates, and hosts 139 of the world's 500 biggest companies. Consumer spending alone has made up 60 to 70 percent of the economy since the 1990s.
The economy grew out of British settlements along the Atlantic coast in the 17th and 18th centuries, trading mostly with Europe but also with Africa and Asia. After independence the former colonies leaned heavily on agriculture. In the 1820s and 1830s mass production began moving work from craftsmen to factories, and stronger patent laws followed. Early industry mostly handled the first steps of processing raw materials, in sawmills, textile mills and shoemaking. Farming kept expanding on abundant land, but other sectors grew so much faster that by 1860 only about half the population was rural.
Growth was bumpy. Nineteenth-century recessions often came with financial panics; the Panic of 1837 opened a five-year depression of bank failures and joblessness. Around 1900, firms exploiting economies of scale and better communications built national operations. People feared monopolies would raise prices, yet many cut costs so quickly that prices fell and output rose, and their workers earned some of the highest wages anywhere. Over about 180 years, per-person income overtook Britain's and the country came to produce roughly a fifth of world output. Downturns since the Second World War seem milder than earlier ones, for reasons nobody fully understands.
Today the country is the world's biggest importer, second-biggest exporter and second-largest manufacturer, and its top trading partners are Mexico, Canada, China, Japan and Germany. It leads the world in producing oil, natural gas and blood products, holds the largest gold reserves, and its dollar is the leading reserve currency. The New York Stock Exchange and Nasdaq are the biggest exchanges on the planet, and research spending has run at about 3.46 percent of GDP since 2023.
Rewards are spread unevenly. In 2026 Americans had the highest median household income in the OECD but also one of the widest income gaps among rich nations, and more billionaires than any other country, worth a combined $5.7 trillion. The labour market is flexible, job security relatively weak, and immigration among the highest anywhere.
