Frequently Asked Questions

Why is "third world country" considered offensive?

Because the term has drifted from its Cold War political meaning into a blanket label for poverty, and it flattens dozens of very different countries into one stereotype of squalor. Development bodies now prefer "developing country", "low-income country" or "Global South".

What is the difference between first, second and third world?

In the original Cold War scheme, the first world was the United States and its allies, the second world was the Soviet Union and its allies, and the third world was everyone unaligned. The "second world" label largely vanished after 1991, which is why only "first" and "third" survived in casual speech, and why the surviving pair now reads purely as rich versus poor.

What should I say instead?

Use "developing country" in general writing, "low-income country" or "lower-middle-income country" if you want the World Bank's actual classification, or name the country. "Global South" works when discussing geopolitics rather than income.
