A value around 28.8 kg/m² is typical (50th percentile) for females in this age group.
Scores above about 34.5 kg/m² fall near the 75th percentile or higher, indicating above-average performance. Scores below about 24.8 kg/m² fall near the 25th percentile; about 75% of the reference population scored higher.
These percentiles reflect the US population, so the same BMI would usually rank at a higher percentile in leaner populations.
