Decisions of women whether to become a mother and timing of the first childbirth significantly participate in the overall ability of a certain society's reproduction, influence the structure of the labour market, mobility and intergenerational relations. Since 1992, the average age of women delivering their first child has been gradually increasing in the Czech Republic and in this connection, the number of primiparas in the older age groups is also increasing. Postponing of maternity to a higher age of a woman influences not only the future structure of the society, but also changes life's careers for women and men. The research project aimed at postponing of maternity wants to take this phenomenon in the statements of late primiparas and identify the processes that participate in their formation. As main research questions we may consider: What are the life careers and reproductive strategies of the late primiparas?, What role did the unrealized maternity play in the life of these women in connection with their partner relationships and professional career?, How have the changes and transformational events in Czech society after the year 1989 projected onto their lives? Which factors for their deciding were the most important?, Do these women perceive their maternity as late?, Which content do they fill this category with?, How does this content connect to other areas of their lives?, Does their maternity lead to any specific form of exclusion? The research will use qualitative (non-standardized interviews) and quantitative techniques (secondary data analysis from the vital statistics of ČSÚ). The research population will be mothers who were 31–40 years old when delivering their first child.
