About the data
How to read this map
Each pin is a country, placed at its geographic center and colored by its youth-literacy rate on a blue scale — deep navy for the lowest rates, bright blue for near-universal. Countries below 70% get a pulsing red ring to mark where the need is greatest.
Who it measures
The World Bank indicator SE.ADT.1524.LT.ZS — the percentage of people ages 15–24 who can read and write a short, simple statement about everyday life.
Global average
Averaged across every country with a reported survey value. The most recent survey per country is used, back to the year 2000.
The estimated pins
High-income countries (the US, Canada, most of Europe, Japan…) aren't surveyed because youth literacy is near-universal. They're shown as a clearly-flagged ≈99% estimate so the map stays complete and honest.
Country pins use World Bank youth-literacy data (ages 15–24), fetched live by data.php and cached for 24 hours. U.S. state and Florida county pins use a closely-related literacy proxy — the share of adults who completed high school (U.S. Census / ACS 2019–23, via USDA ERS) — so zooming into the United States reveals every state and all 67 Florida counties.
