A comparison is made between the birth weights, weights, heights, skinfold thicknesses, and head circumferences of two groups of Tokelauan children aged under 15 years. One group was living in Tokelau on their three home atolls and the other group was living in New Zealand. The children living in New Zealand were in general heavier, taller, had more body fat and larger head circumferences than the children living in Tokelau.
