The dissertation deals with the exploration of the Czech rural family as an ecosystem. The family ecosystem includes a summary of family member interactions with each other, as well as interaction with other natural or socio-cultural systems. Nowadays, the families differ considerably in their arrangement, size, style of family life and other characteristics. These differences are much greater between cities and rural areas, and so are the differences in different countries. The aim of the dissertation was to determine the significant characteristics of the life of Czech families in the country in international comparison. A sociological survey was conducted in the South Moravian Region. The questionnaire survey was also conducted in Ukraine for comparison. International comparisons have also been made using knowledge from the European Social Probe. The paper noted the differences in family life between cities and the countryside, consisting, among other things, in different housing and service conditions and closer family relations in the countryside. The differences between family life in the Czech Republic and Ukraine seem to depend on the different rates of unemployment and the significantly greater conservatism of Ukrainian rural life.
