South-east Asian components of our population are increasing rapidly. The ethnic mix in each organisation is likely to be quite different, so the best approach may be to develop anthropometric distributions for each organisation from different data sets, using the proportions of each ethnic group.

Reach distances on a horizontal work surface may be divided into a "Normal work area" and a "Maximum work area". .
