What these numbers imply
The figures below are not published directly by the WHO. Each one is calculated from the official length-for-age and 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 |
|---|---|---|
| Growth over the next 3 months | +3.2 cm | The 50th percentile rises from 77.5 cm to 80.7 cm over the following 3 months. Derived from adjacent rows of the same WHO table. |
| Growth since birth | +28.4 cm | The 50th percentile at birth is 49.1 cm; at this age it is 77.5 cm. |
| Spread between 3rd and 97th percentile | 10.3 cm | At this age the middle 94% of girls fall between 72.4 cm and 82.7 cm. |
| Difference from boys at the same age | -1.6 cm | The 50th percentile for girls is 1.6 cm shorter than the 50th percentile for boys. |
| Median weight and resulting BMI at this age | 9.6 kg · BMI 16.0 | Combining the 50th percentile of weight (9.6 kg) with the 50th percentile of length (77.5 cm) from the WHO weight-for-age and length-for-age tables. |
These are population reference statistics only. They describe how a group of infants of this age and sex is distributed, and say nothing about any individual child.
How to read this table
For this table, the percentile is a position in the cited reference distribution for children of the same sex and completed age band. The 50th percentile is the median: about half of the reference observations are lower and half are higher. A percentile is not a forecast, target, diagnosis, or measure of an individual child’s health. Measurement method and the reference chart used can change the reported position.
Measurement: WHO reports recumbent length for children under age 2; the page title follows the common height-chart search phrase.
