In plain words
63.9% of adults
What it is. People aged 15 and over who can read and write a short, simple statement about everyday life, as a share of that age group.
Higher is better. A rise in adult literacy rate is generally good news; a fall, bad news.
Why it matters. A percentage puts countries of different sizes on the same footing, so it can be compared across borders and over time.
