1. Facts from public sources
Every list is tied to one source that publishes real numbers or real charts:
- Apple charts: the most-played songs in 15 countries and albums in 10, plus the top podcasts and apps.
- Wikipedia pageviews: what the world read yesterday, in 16 languages.
- World Bank: population, economy and environment, country by country.
- Wikidata: the tallest, longest, largest and oldest things on Earth.
- GitHub, Steam and Open Library: the most-starred software, the most-played games, the most-read books.
A handful of records that rarely change, like the highest mountains, were verified by hand against Wikipedia.
2. Refreshed around the clock
Every 30 minutes, the engine checks which lists are due. Charts refresh daily, slow-moving records weekly or monthly. Each list shows when it was last updated and how often it refreshes.
3. Checked before it’s published
A new ranking only replaces the old one if it passes every check:
- it has at least 10 entries,
- no entry appears twice,
- every entry links to its source,
- and the top 10 hasn’t changed suspiciously all at once.
If a check fails, the previous version stays up. Arrows next to each entry show how it moved since the last update.
Why top 10?
Ten is enough to be meaningful and short enough to read at a glance. We keep the top 50 behind every list, so you can always expand past the first 10.
No opinions, no AI guesses
Every number comes from its source. Nothing is ranked by opinion or written by AI. If public data can’t rank something, it isn’t on Top Facts.
