WebCalculate the index of dissimilarity between two population structures. A returned value of zero means that the two population have identical structure. A value of 100 means that the populations have no overlap at all (not likely for populations structured only by age). This is a simple measure of distribution overlap on the absolute scale. WebAn index value of 0 indicates perfectly proportionate distribution. An index value of 100 indicates the opposite spatial distribution. This appears to be used more to measure ethnic segregation (oddly enough) because you would use one group of people as apples and others as oranges.
