AB In recent years, both scientific and judicial sources have highlighted the need for more knowledge about minutiae  variability, in order to improve their statistical application to  fingerprint identification. In line with this trend toward improving our  knowledge of this subject, the aim of the present study was to  calculate the frequency with which 20 types of minutiae  appeared in 2780 fingerprint impressions obtained from 278 individuals  from two Argentinian population samples (100 individuals from Ramal and  178 from Puna&-Quebrada). The different types of minutiae were  located, identified, and quantified visually in two areas on the  fingerprint, the inside and outside of a circle, the radius of which cut  fifteen ridges perpendicularly, starting from the center cut of the  axes defining the sectors. The non-equiprobability found in both  population samples for the different minutiae types studied  demonstrated that the evidential weight provided by these  characteristics is not the same when applied in identification  processes, whether used quantitatively (numerical standard) or  qualitatively (holistic method). The results obtained for both  populations were compared statistically with those published previously  for a Spanish population sample, which had been collected using the same  methodology. This comparison has enabled us to demonstrate, for the  first time, the existence of significant differences between populations  in minutiae frequencies, independently from the main pattern type.
