Ethnic fractionation (EF) refers to the number, size, socioeconomic distribution, and geographic location of particular cultural groups, usually within a state or some other territory. Specific cultural characteristics may refer to language, color, religion, ethnicity, customs and traditions, history, or other distinctive criteria, either alone or in combination. Often these traits are used for social isolation and monopolization of power. The ethnic factionalism index in Germany is 0.1682. This means that people living in Germany come from a narrow group of ethnic groups, all of which are related to each other. EF is usually measured as 1 minus the Herfindahl concentration index of ethnolinguistic group shares, which reproduces the probability that two randomly selected individuals from a population belong to different groups. A theoretical maximum EF of 1 means that each person belongs to a different group. Read the German statistics on average age and gender distribution at different ages below.
