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 |
|---|---|---|
| Weight gain over the next 12 months | +1.7 kg | The 50th percentile rises from 12.7 kg to 14.4 kg over the following year. Derived from adjacent rows of the same CDC table. |
| Spread between 3rd and 97th percentile | 5.2 kg | At this age the middle 94% of boys fall between 10.4 kg and 15.7 kg. Weight varies far more than height at the same age. |
| Share of the age-20 median reached | 18.0% | The 50th percentile here is 12.7 kg; the CDC table ends at age 20 with a 50th percentile of 70.6 kg. |
| Difference from girls at the same age | +0.6 kg | The 50th percentile for boys is 0.6 kg heavier than that for girls at this age. |
| Median height and resulting BMI | 86.9 cm · BMI 16.9 | Combining the 50th percentile of weight (12.7 kg) with the 50th percentile of stature (86.9 cm) from the CDC weight-for-age and stature-for-age tables. |
