This article highlights the main factors – subsystems that affect the development processes of ethnic groups. A mathematical model of ethnic groups is constructed and a computer study of this system is carried out. A qualitative study of the dynamic system of ethnic groups is carried out for the case when political differentiation and the degree of adaptation is constant. Relations are written out characterizing the number of equilibrium states, their type, the number of singular points at infinity, and phase portraits are presented using application programs. This computer study on a given set of characteristics will allow you to simulate the occurrence of problem situations and make changes in advance.
