Ridge width influences the number of ridges present in a specified area of a fingerprint – epidermal ridge density – and several researches have been carried out on this aspect of fingerprints. The present study has been carried out to examine ridge density differences in two Northern Indian populations (Sikh Jat and Bania). The authors are not aware of any research on differences in ridge density among the Sikh Jat and Bania populations of Punjab, except anthropological studies. In the present study it has been found that 92% of Sikh Jat females have a mean ridge density above 13, whereas 76% of Sikh Jat males have (a mean ridge density) below 13, while in Bania, 100% of females have mean ridge density above 14 and 80% of males – below 14. The study suggests that there are significant differences in epidermal ridge density between males and females within each of the two populations, and also significant differences between the two populations. This study will provide additional information for the fingerprint examiner in analyzing finger impressions and narrowing down an investigation involving a large number of samples.
