sAnteil

sAnteil is a term used in some German-language statistical and analytical writings to denote the share or proportion of a total quantity attributed to a specific subcomponent indexed by s. It is not a universally standardized mathematical symbol, and its exact meaning can vary by context. A common formalization defines sAnteil as A_s / A_total, where A_s is the contribution of component s to the total A and A_total is the sum of all contributions A_s. The value is typically expressed as a fraction or a percentage.

In practice, sAnteil appears in diverse fields. In economics, if B_s is the budget allocated to sector s and B is the total budget, then sAnteil = B_s / B. In demography, if N_s denotes the population in group s and N_total the total population, then sAnteil = N_s / N_total. In ecology or energy studies, one may use sAnteil to describe the share of a quantity such as biomass, energy, or emissions attributable to a category s.

Usage considerations include the dependence on the chosen denominator and the index s. Different definitions of A_total or different groupings for s can change the resulting sAnteil, so it is important to specify the exact quantities involved when using the term. Related concepts include Anteil (share) and market share (Marktanteil).
