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 | +1.8 kg | The 50th percentile rises from 52.1 kg to 53.9 kg over the following year. Derived from adjacent rows of the same CDC table. |
| Spread between 3rd and 97th percentile | 42.1 kg | At this age the middle 94% of girls fall between 39.6 kg and 81.6 kg. Weight varies far more than height at the same age. |
| Share of the age-20 median reached | 89.6% | The 50th percentile here is 52.1 kg; the CDC table ends at age 20 with a 50th percentile of 58.2 kg. |
| Difference from boys at the same age | -4.4 kg | The 50th percentile for girls is 4.4 kg lighter than that for boys at this age. |
| Median height and resulting BMI | 161.9 cm · BMI 19.9 | Combining the 50th percentile of weight (52.1 kg) with the 50th percentile of stature (161.9 cm) from the CDC weight-for-age and stature-for-age tables. |
