Average BMI for 16-Year-Old Females in the U.S.: CDC Data

According to the Centers for Disease Control and Prevention (CDC), the average Body Mass Index (BMI) for 16-year-old females in the United States is 21.3.

Context & Interpretation

• This is a population mean from NHANES data, not a target or ideal.
• BMI-for-age percentiles are used for adolescents, not adult categories.
• A BMI of 21.3 at age 16 typically falls around the 50th–60th percentile (healthy weight range).

Important Caveats

• Individual health assessment requires growth charts, body composition, puberty stage, and clinical evaluation.
• BMI does not distinguish muscle from fat; athletic teens may have higher BMI.
• Focus on healthy behaviors (nutrition, activity, sleep) rather than a number.
