Why Heights Differ: Genetics, Nutrition, and Trends
Height is roughly 80% genetic and 20% environmental, but nutrition in the first years of life matters enormously at the population level. Tonga's Polynesian averages are among the world's taller Pacific profiles.
Like most populations, Tonga has seen height changes across generations as nutrition, sanitation, and healthcare evolved.
Comparing your personal height to Tonga's average is informative, but percentile rankings depend on which reference population you use. Our calculator compares against US CDC/NHANES data, which may differ from Tonga's national distribution.
