Postnatal Growth

A 2010 paper on head growth in Nigerian children of the Ijaw tribe has data for head circumference, facial height, nasal height, and many other parameters (1). The study was small (70 people per group) and data was somewhat uneven. However, Figure 3 shows mean head circumference values in Ijaw children and adolescents aged 3 to 18. We have used the data to create two figures with 10th, 50th, and 90th percentiles, but there are clearly inaccuracies. The figure in the paper is probably more accurate.

Head Circumference

Size at Birth

The data here was taken from a freely available study of size at birth among infants born to economically advantaged children in Maiduguri, a city in northeastern Nigeria (2). The authors measured 760 boys and girls from several different tribes and presented mean size by tribe and mean size of the entire group.
