When the time comes to enroll a child into kindergarten, parents are usually those who decide which type of kindergarten is the first choice for their child. Catholic parents in Zagreb often choose between putting their children in private catholic or city-owned kindergarten. Their final decision is influenced by the availability of preschool educational institutions. The goal of this thesis is to explain the statistical methods used in this thesis, to determine existence of differences between parents who enroll children into private catholic or city-owned kindergartens based on characteristics of religion, socio-economic status and political orientation and to find out are there any differences in characteristics of religion and political orientation between younger and older parents. For the need of this research a poll was done with questions about socio-economic status, characteristics of religion and political orientation of the parents. Poll is fulfilled by 171 examinee. Collected data are presented in descriptive way expressed in tabular and graphically using histograms and then by conducting statistical tests Mann-Whitney U and 2 (chi-square) test, to establish differences between examinees whose children are attending private catholic or city-owned kindergartens and between younger and older parents. Hypotheses of the thesis are that there are significant differences in both cases. Results of this research partially confirmed both hypotheses. In favour of the first hypothesis it is shown that parents of children enrolled into the private catholic kindergartens posses considerably more real estates, have higher educational level and household income. Also, there is significant difference on the scale of attitudes towards liturgy, importance of prayer and non-liturgical contents provided by the Church. There is no significant difference in political orientation between those two subsamples. Comparison of younger and older parents revealed considerable differences on the same three variables of religiosity, older parents also emphasize importance of prayer, liturgy and non-liturgical contents provided by the Church, contrary to political orientation for which there is again no significant difference.
