The social protection is a fundamental component of the European type of society. It can be understood as an expression of the set of collective changes meant to protect people against some social well defined risks. The functioning of the social protection systems supposes important costs and, therefore, the corresponding allocation of financial resources. At present, the costs of the social protection engross and stimulate an important proportion of the financial and human resources at the European states’ level. Thus, on the whole of the European countries UE-25, the costs of the social protection represent more than a quarter from the Gross Domestic Product (28% in 2005), almost half of the public budgetary expenditures, with very important variations from one country to another.
