According to the World Health Organization (WHO), Body Mass Index (BMI) is a statistic that indicates the ratio of a person's weight to their body volume. The Center for Disease Control (CDC) uses the table to classify children from ages 2 to 20. Because BMI values change as children grow, the CDC uses percentiles rather than fixed values for BMI. Percentiles provide a basis of comparison for BMI over time.

According to the World Health Organization (WHO), Body Mass Index (BMI) is a statistic that indicates the ratio of a person's
weight to their body volume. The Center for Disease Control (CDC) uses the table to classify children from ages 2 to 20.
Because BMI values change as children grow, the CDC uses percentiles rather than fixed values for BMI. Percentiles provide a
basis of comparison for BMI over time.
Weight status Percentile range
Underweight Less than the 5th percentile
Healthy weight 5th percentile to less than the 85th percentile
Overweight
Obese
85th to less than the 95th percentile
Equal to or greater than the 95th percentile
Based on data from WHO, a representative sample of 11-year-old females could consist of the following 15 values.
15.8, 16.1, 13.7, 15.3, 19.2, 14.7, 18.1, 16.8, 18.6, 19.9, 16.5, 17.7, 17.2, 27.0, 21.4
