21 indicators · 217 countries · 156,366 observations. Each indicator is read at the most recent year that still has near-complete coverage. Neither rule works alone: child stunting's newest year has six reporters, and internet use is best covered in 1990, when nearly every country reported it as zero.

How much of the world was measured
Best year 2018 with 93 of 217 · most recent 2025 with 4. A short bar means the world did not measure, not that the value fell.
· Survey-based and irregular — many countries report only every few years, and some not at all.
· Usually measures consumption in poorer countries and income in richer ones, which limits strict comparability.
What we can actually see
Coverage is wildly uneven, and that unevenness is a finding rather than a footnote. Life expectancy is near-universal; the survey-based indicators are not. Sorted by how much of the world reports at all.
