Life expectancy: 57 sourced records

What this topic measures

This is a population estimate at birth, not a maximum lifespan or a prediction for one person. The unit is years. This topic uses ratio scoring: a value half the target and a value twice the target are equally far away, so think in multiplicative bands rather than fixed steps.

A record is a named row in the frozen catalog, not necessarily a unique entity. Some topics contain several records with the same value, and a name round accepts any record at the closest distance. The table below is the complete answer set for this topic; there is no hidden shortlist.

All 57 records

Every row links to the original source used for that record. Values are rounded for display only; the scoring engine uses the stored source value. The snapshot date and unit are part of the topic’s definition, so a current live figure may differ.

The table has 57 rows, one for each accepted record. It does not list every alias or spelling variant; the game’s name matcher handles those at answer time. If two records share a value, both remain separate rows.

The range and the gaps

The 57 records run from 54.5 years to 84.2 years. The median is 78 years, with a middle half from 73.4 years to 81.9 years. The largest adjacent gap is 9.2 years between Nigeria and Kenya. Every record has a distinct value in this snapshot.

The highest listed records are Switzerland (84.2 years), Japan (84 years), Spain (83.9 years). The lowest are Nigeria (54.5 years), Kenya (63.7 years), Ghana (65.5 years). Use these as anchors before you make a ratio or year estimate; the table below gives every value.

What the table does not tell you

These are single snapshot values in years for 2023 World Bank snapshot · 57 selected countries. The table is not a time series, a range of typical values or a measure of uncertainty. A source can round, revise or use a different definition in a later release; the game uses the stored snapshot for every score. Read the source and the record label before treating a value as a current live measurement.

How to estimate this topic

Life expectancy is years at birth for the source’s year, not a prediction for an individual and not healthy life expectancy. Use 50, 70 and 80 years as bands. A one-year difference is small; a ten-year difference is a strong signal.
