Our Data
An open evaluation of name-to-nationality inference
We evaluate Nationalize against public datasets in which each person's nationality is already recorded, reporting how often the true country lands in our top 1, 3 and 5 for every set. Each individual prediction is listed below, so the aggregate figures can be checked and reproduced.

Method
How we measured this
Population. We score the "alive-today" set: people with a known birth year, at most 80 years old.
Top 1 / 3 / 5 is how often the true country lands at rank 1, within the first 3, or within the first 5 of our ranked shortlist. MRR@5 rewards ranking the right country higher, not just somewhere in the list.
Why politicians score higher. Distinctive, less-Anglicised names are often tied to a single country, so a globally diverse set can be easier to place than a Western-skewed one.
Rounding. Figures are the exact measured value to two decimals — we never round accuracy up.
