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 | +2.1 kg | The 50th percentile rises from 15.9 kg to 18.0 kg over the following year. Derived from adjacent rows of the same CDC table. |
| Spread between 3rd and 97th percentile | 8.5 kg | At this age the middle 94% of girls fall between 12.8 kg and 21.3 kg. Weight varies far more than height at the same age. |
| Share of the age-20 median reached | 27.3% | The 50th percentile here is 15.9 kg; the CDC table ends at age 20 with a 50th percentile of 58.2 kg. |
| Difference from boys at the same age | -0.4 kg | The 50th percentile for girls is 0.4 kg lighter than that for boys at this age. |
| Median height and resulting BMI | 101.0 cm · BMI 15.6 | Combining the 50th percentile of weight (15.9 kg) with the 50th percentile of stature (101.0 cm) from the CDC weight-for-age and stature-for-age tables. |
