Each fact tile shows one observation, such as a high point, coastline length, median age or GDP. Subjects rotate every UTC day. Missing observations are omitted. Display values are rounded for readability; reference years and estimates appear on each tile.
Elevation, coastline and median age: CIA World Factbook, via a pinned CC0 factbook.json archive. The Factbook was discontinued in February 2026: these are archived observations, not live measurements. Other statistics use the 2023 World Bank snapshot credited above. Area uses the ODbL country catalogue.
Observations, source links and exceptions ↓CC0 1.0Coastline length depends on the measuring method. Median age divides the population into equally sized younger and older halves; it is not life expectancy. Known conflicting heights are omitted or separately corrected with a verifiable source.

Disputed capital questions and selected sensitive border questions are excluded. Pinpoint uses simplified country boundaries with a 25 km tolerance. Comparison questions use 2023 observations. Silhouettes show simplified main landmasses; small and remote islands may be omitted.
