This Master Theses deals with the changes of the family and marriage in last century. The changes in the character of Czech demographic behaviour, in the field of reproduction, represent consequences of a modern cultural change, whose bearers are contemporary young Czech generation.The low marriage rate and birth rate are inevitable phenomena accompanying these cultural changes.
