Nauru

NR

Oceania

Nauru is home to 2 documented ethnic groups in Oceania — led by Nauruan (~89%), Nauru Other (~11%). This page blends their phenotype and demographic data into one weighted reference: skin tone, facial features, hair texture and build, drawn from published census and ancestry sources.

Demographic Composition

Composition weights are derived from self-identification in published census and demographic surveys. Each row links to the source ethnic-group atlas page.

Ethnic groupWeightSource

Nauru's distinctive demographic profile reflects its isolated position approximately equidistant between Micronesia, Polynesia, and Melanesia

Nauru Phenotype Profile

Nauru has a strongly Nauruan demographic profile (~89%). The country is the third-smallest globally and has experienced documented continuing economic challenges since the depletion of phosphate reserves in the 1990s.

A descriptive view, not a claim about individuals

This page shows a weighted aggregate of phenotype observations across the Nauru population, based on demographic composition from published census and ancestry sources. Phenotypes within any country are far more varied than the aggregate suggests; this is a descriptive reference, not a deterministic claim about any individual. For source-level detail on individual ethnic groups, see the constituent atlas pages linked below.

Methodology Notes
