Waist Circumference: Females, Age 30-39
What these numbers mean
A value around 93.1 cm is typical (50th percentile) for females in this age group. The middle 50% of the reference population fall between about 83.9 cm and 108.8 cm; values below or above that central range sit in the lower or upper half of the distribution.
These percentiles reflect the US population, so the same waist circumference would usually rank at a higher percentile in leaner populations.
