Overview

• Across 25 nations, medians view five issues as major threats: false information online 72%, global economic conditions 70%, terrorism 69%, climate change 67% and infectious diseases 60%.
• Concern about the global economy has climbed in most countries since 2017, with large increases in places like Germany, Canada, Sweden, the Netherlands and Poland, and is generally higher in middle-income countries.
• Worry about infectious disease has dropped sharply in advanced economies since COVID-19 peaks (to a median 50% in those nations in 2025) but remains very high in several middle-income countries such as Kenya, Turkey, Indonesia and Mexico.
• Climate concern is higher than in 2013 yet has eased since 2022 in several high‑income countries; no country rates climate change as the top threat, and ideological gaps are pronounced, especially in the U.S.
• Perceptions differ by country context: misinformation leads in Germany, the Netherlands, Poland, Sweden, the UK, the U.S. and South Korea; the economy leads in Greece and Australia; terrorism leads in India, Israel, Nigeria and Turkey, while disease leads in Argentina, Brazil and South Africa.
