Arseniy Petrovich Khomenko (1898-1939) is an outstanding Ukrainian demographer and sociologist who made a significant contribution to the study of demographic processes and social transformations in Ukraine. In 1930 he published the fundamental monograph “The Family in the Process of Perestroika”, which became an important study in the field of demography and sociology of the family. In this work, Khomenko investigated changes in the structure and functions of the family in the conditions of socio-economic transformations of Soviet society in the late 1920s and early 1930s. He developed a classification of families by the number, composition and economic activity of their members, which remains relevant today. He also analyzed the stability of marriage, the causes of the spread of loneliness and the prospects for the development of a small family. The scientist paid special attention to the role of the female mother and her economic activity, believing that the economic activity of women is the main condition for gender equality. The monograph "Family in the process of perestroika" combines detailed demographic studies with a deep sociological analysis of new social phenomena, which makes it a valuable source for studying the history of the family and demographic processes in Ukraine. To date, the original editions of this book are rare. There are stamps of libraries
