This article deals with the problem of inclusion of vulnerable groups in society on the example of elderly and disabled people of working age. The article gives a theoretical overview of approaches to the problem of social inclusion in Russia and abroad, the main strategies of social inclusion, implemented in relation to the study groups. The article also presents the results of empirical research conducted on the basis of two typical social budget institutions of St. Petersburg and the public organization “Children of war”. Based on the results of the analysis of theoretical materials and sociological research, the authors conclude about the limited nature of the currently implemented strategies of inclusion in society for the elderly and disabled. It is also noted that, although at the moment for the representatives of the studied groups it was possible to successfully overcome social isolation, their social integration remains an urgent problem.
