What these numbers imply
The figures below are not published directly by the CDC. Each one is calculated from the official weight-for-age tables so that this page answers questions the raw dataset leaves open. Values differ for every age and sex.
| Measure | Value | How it was derived |
|---|---|---|
| Spread between 3rd and 97th percentile | 46.8 kg | At this age the middle 94% of boys fall between 54.0 kg and 100.8 kg. Weight varies far more than height at the same age. |
| Share of the age-20 median reached | 100.0% | The 50th percentile here is 70.6 kg; the CDC table ends at age 20 with a 50th percentile of 70.6 kg. |
| Difference from girls at the same age | +12.4 kg | The 50th percentile for boys is 12.4 kg heavier than that for girls at this age. |
| Median height and resulting BMI | 176.8 cm · BMI 22.6 | Combining the 50th percentile of weight (70.6 kg) with the 50th percentile of stature (176.8 cm) from the CDC weight-for-age and stature-for-age tables. |
