The “elephant graph” (also called the elephant curve) shows how income growth was distributed across the entire world population over roughly two decades of globalization. Named for its shape, which resembles an elephant with a raised trunk, the graph reveals a striking pattern: the global middle class and the very richest people saw large income gains, while the lower-middle and working classes in wealthy countries saw almost none. It was developed by economist Branko Milanovic and first published in 2012, drawing on household survey data from 1988 to 2008.
How to Read the Graph
The horizontal axis ranks every person on Earth by income, from the poorest on the left to the richest on the right. The vertical axis shows how much each group’s real income grew over the period studied. What emerges is a line that rises into a hump around the middle of the distribution, dips sharply near the 80th percentile, then shoots upward at the very far right. That hump is the elephant’s back, the dip is where its head meets its trunk, and the sharp rise at the end is the trunk itself, reaching skyward.
The shape tells a story in three acts: who won from globalization, who lost, and who won the most.
The Hump: Asia’s Rising Middle Class
The large bulge in the middle of the graph, roughly spanning the 50th to 90th global income percentiles, represents hundreds of millions of people in emerging economies, predominantly in China, India, and Southeast Asia. These groups experienced enormous real income growth, peaking near 250% between 1980 and 2016 in some analyses. Factory jobs, trade expansion, and urbanization pulled vast populations out of poverty and into a new global middle class.
This is the part of the elephant graph that represents globalization’s clearest success story. Between 1980 and 2016, the bottom 50% of the world’s population captured about 12% of total global income growth. Much of that went to workers in developing countries whose living standards improved dramatically within a single generation.
The Dip: Stagnation in Rich Countries
The most politically significant part of the graph is the valley just before the trunk, around the 75th to 85th global income percentile. This group experienced essentially zero real income growth over two decades. These aren’t poor people by global standards. They are the lower-middle and working classes of wealthy nations: factory workers in the American Midwest, service employees in southern England, wage earners across much of Western Europe and Japan.
Their incomes flatlined even as the global economy expanded. Manufacturing moved overseas. Wages stagnated while housing, healthcare, and education costs climbed. The elephant graph gave this frustration a visual form. Analysts at the Brookings Institution and elsewhere have pointed to this trough as a data-driven explanation for the populist political movements that swept through rich democracies in the 2010s, from Brexit to the 2016 U.S. presidential election. Voters in that dip weren’t imagining their situation. The global data confirmed it: they were the one group globalization largely passed over.
The Trunk: Gains at the Very Top
At the far right of the graph, the line rockets upward. This is the trunk, representing the global top 1%, who captured a staggering 27% of all income growth between 1980 and 2016. To put that in perspective, the richest 1% took home more than twice the share of growth that went to the entire bottom half of the world’s population combined.
This group includes executives, financiers, tech entrepreneurs, and wealthy professionals concentrated in North America, Europe, and parts of East Asia. Their gains came from rising asset values, globalized capital markets, and compensation structures that increasingly rewarded those at the top. The trunk’s steep upward slope makes the inequality visually unmistakable: no matter how much the global middle class gained, the wealthiest gained far more.
Why the Graph Became So Influential
Before the elephant graph, debates about globalization tended to break into two camps. Proponents pointed to billions of people lifted out of poverty. Critics pointed to hollowed-out factory towns in the West. The elephant graph showed both sides were right, and it showed exactly where the pain was concentrated. It compressed decades of complex economic data into a single image that anyone could understand.
It also reframed inequality as a global phenomenon rather than a national one. Within any single country, income statistics might look unremarkable. But when you line up the entire world’s population and ask “who benefited?”, the answer is sharply uneven. The emerging-world middle class and the global elite both did well. The developed-world working class did not.
Criticisms and Limitations
The elephant graph is not without its critics. One major concern is that it compares income percentiles at two points in time, but the people in those percentiles aren’t the same individuals. China’s rapid growth shifted enormous populations up the income ladder, meaning the “middle” of the global distribution in 2008 contained very different people than the “middle” in 1988. The graph shows what happened to positions in the income ranking, not necessarily what happened to specific households.
Some researchers have also noted that the depth of the trough (the dip before the trunk) changes depending on whether you adjust for population shifts between countries. When reweighted to account for where population growth actually occurred, the dip becomes less dramatic in some versions. Still, even revised analyses preserve the graph’s basic shape and its core message: income growth during the era of globalization was wildly unequal, and the working classes of rich nations absorbed a disproportionate share of the cost.
