How this ranking works

For annual statistics, the default is the newest year covering at least 70% of the maximum available country coverage, and at least 20 economies where possible. A ranking uses one year or report edition; missing observations are not replaced with another year. Newer years with lower coverage can be selected.

Intentional homicide rates and peace scores rank from lowest to highest; other indicators rank from highest to lowest. Ranks use original values and competition ranking for ties, for example 1, 2, 2, 4. Filtering or changing display order does not recalculate global ranks. Higher values are not necessarily better.

Statistics reflect the public source snapshot, not live measurements. Some series are modeled estimates or multi-year averages. See original metadata.
