Objective To discuss whether there are differences in fingerprint ridge density between the males and the females and what the specific differences are. Method A total of 120 males and 120 females (all were college students in Fujian) were selected, and the fingerprint ridge densities of these 240 Han youths were counted. According to Acree method, the radial upper part of the core region of the fingerprint center was selected for analysis, because the fingerprint pattern types in this region all presented similar ridges. This method was used to isolate the ridge in a certain area, so as to facilitate the counting. A 5mm×5mm grid was designated as a counting area on the middle radial part of the fingerprint for identification. Fingerprint ridges in the unit area were counted, then the average was calculated, and finally SPSS software was used to process and analyze all the data obtained. Result For the females, the average ten-fingerprint ridge density was basically above 14 ridges/ 25mm2; and for the males, it was basically below 14.5 ridges/25mm2. Conclusion There are some differences in the density of ten-fingerprints between men and the females, and the females’ is generally higher than that of the males.
