title: Alternative explanations of the dependence of the density of centers on the density of population.
abstract: "The paper is devoted to modeling the relationship between the density of service centers and the density of population (or...the density of demand).  Several models lead to an exponential function with the exponent equal to [two-thirds].  For a number of real systems of centers, the power is considerably different from [two-thirds] (more often it is nearer to 1).  I describe a series of models that explain this difference." The application of the model to U.S. data is discussed.
