Nasal index is an ethnic sensitive anthropom etric index. It is an important anthropometric parameter for classifying the race and sex of an individual whose identity is unknown. This study was carried out to compare the nasal indices between the Ekpeye and the Ikwerre ethnic groups of Rivers State in Nigeria. Five hundred (500) subjects were randomly selected from each ethnic group who were purely of either Ikwerre or Ekpeye origin by both parents and grand parents. These comprised two hundred and fifty (250) males and two hundred and fifty (250) females. The age of the subjects ranged from 18-32 years.Nasal height (NH) and breadth (NB) of these subjects were measured using a sliding caliper and nasal index (NI) was calculated as NB/NH×100.The result was analyzed statistically using z-test.The result showed that the Ekpeye males and females had mean nasal indices of 93.72±0.57 and 88.99±0.61, respectively while the Ikwerre males and females had mean nasal indices of 84.81±0.57 and 93.17±0.51. These values w ere significantly different between the two group (p<0.05). The mean nasal index of the Ekpeyes irrespective of gender was found to be 93.36±0.59 and that of the Ikwerres was 88.99±0.54.The Ekpeye males, Ekpeye females and the Ikwerre females had a nasal index which is above 85 and so fall within the classification platyrrhine while the Ikwerrre males had a nasal index between 70.00 and 84.9 so fall within the mesorrhine nose type. The data obtained showed difference in nose types. Thus the data of this study is recommended in anthropological studies and reconstructive surgery amongst the ethnic groups under study.
