Definition Social diversity ratio - reflects a measure of the degree of diversity of a territorial unit. It varies between 0 (maximum specialization) and 1 (maximum diversity). For each territorial unit, the calculation of this indicator is established by the following steps: 1) the product between the weight of each socioeconomic group in the territorial unit's population and the natural logarithm of this weight; 2) the sum of the values obtained for every socioeconomic group; 3) the division by the natural logarithm of the number of socioeconomic groups considered; 4) the adoption of the symmetrical value obtained.
