The thesis examines to what extent more recent demographic changes have been reflected in the spatial organization of primary education system on the territory of the Sisak and Moslavina County. The analysis ofspatial changes in primary education has been conducted at the level of municipalities and towns, as well as two larger spatial organisational units of the Sisak and Moslavina County–Sisak Posavina and Moslavina as one and Banovina as the other, in the period between 2001 and 2015. Therefore, the initial analysis included demographic processes resulting in total depopulation and the decrease in the number of children enrolled in primary schools (migrations and natural relocation of the population). A more detailed analysis included population censuses from 2001 and 2011, on the basis of which the following data are presented: an overview of the total population count, number of primary school children, and the coefficient of femininity and masculinity for the total population as well as for the primary school contingent. In the second part of the thesis the analysis is directed towards spatial changes in primary education which emerge as a consequence of the abovementioned processes (changes in the number of pupils, schools, classes and teachers). On the basis of the analysis of the spatial changes in primary education some indicators of the average number of children per class, average pupilteacher ratio an the average number of pupils per school have been calculated. Th reduction in the number of children for whom primary education is compulsory is for the time being more pronounced than the dynamics of the reduction in the number of classes, branch schools or central school statuses, whereas the number of teachers has even increased. Significant differences in population density and the level of socio-economic development in certain parts of Sisak and Moslavina County are also manifested in the differences in spatial organization of the educational system.
