In practice
For an article or research report, ask how a country's life expectancy changed over ten years, then check the source, years and definitions.
Why it matters
Researchers, students and journalists often need figures scattered across agencies. A shared search platform can help locate the underlying statistics.
Limits
We checked the announcement but have not queried the service. Chinese-language results and indicator coverage remain unverified. Correlation in a chart does not establish causation.
