By many measures, President Biden is very unpopular. Since at least World War II, no president has had a worse disapproval rating at this point in his term.

Relative to his international peers, however, Biden looks much better. Many leaders of developed democracies have disapproval ratings even higher than Biden’s, as this chart by my colleague Ashley Wu shows:

Many world leaders are also up for re-election. More than 60 countries — half of the world’s population — will vote or have voted this year. Most of the countries in the chart above will vote in national or European Union elections in the coming months.

Why are people so upset with their leaders? Some explanations are local, but four global issues have driven much of the public’s anger. Call them the four I’s: inflation, immigration, inequality and incumbency.

The world has seen a sharp increase in prices over the past few years. As bad as inflation has been in the U.S., it has been worse in European countries more directly affected by Russia’s invasion of Ukraine.

Rising prices anger voters. Your hard-earned money is worth less. “When prices rise, it feels like something is taken away from you,” my colleague Jeanna Smialek, who covers the U.S. economy, has said. And people direct much of that anger toward their leaders.
