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 since birth | +36.1 cm | The 50th percentile at birth is 49.9 cm; at this age it is 86.0 cm. |
| Spread between 3rd and 97th percentile | 11.1 cm | At this age the middle 94% of boys fall between 80.5 cm and 91.6 cm. |
| Difference from girls at the same age | +1.4 cm | The 50th percentile for boys is 1.4 cm longer than the 50th percentile for girls. |
| Median weight and resulting BMI at this age | 11.8 kg · BMI 16.0 | Combining the 50th percentile of weight (11.8 kg) with the 50th percentile of length (86.0 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.
