Changing the political system in the Czech Republic after 1989 have not brought only a transformation in the economic and social fields, but also began to rapidly transform until relatively stable demographic patterns of reproduction. These changes in reproductive behavior patterns are often called in literature as the second demographic transition.
Beginning to weaken the family functions and conversely showing a different priority of each individual and increasing individualism. The aim of the following article is to introduce the temporal and spatial changes in the level and structure of fertility in the districts of the Czech Republic.
In particular, there will be outlining the development of spatial differentiation and emphasis will be put on the determination of the innovative districts or those districts where there is a transformation of fertility patterns first. The basic assumption of the present study is the application of the concept of the second demographic transition to changes in reproductive behavior of the population in the districts of the Czech Republic.
The theoretical basis for the study of geographic patterns of site conversion reproductive behavior of the population is a developmental process and the dynamics of change propagation in space or geographic diffusion process. Were analyzed three indicators, total fertility rate, the average age at first birth and the proportion of live births outside marriage, which best characterize the changes in the level and structure of fertility in the Czech districts after 1989.
