A household’s financial security is essential for the satisfaction of the needs and wants of its members, both communal and individual. It constitutes a kind of foundation for all of a household’s financial decisions that impact its standard of living. The article aims to assess the level of financial security of Polish households in 2005–2013. The research draws on data from Genworth Index, HBS conducted by the Central Statistical Office (GUS) and Social Diagnosis (Diagnoza społeczna) overseen by the Social Monitoring Council. The study shows that Poland is characterized by a low level of financial security relative to other European countries, especially Western and Scandinavian. More than three-quarters of Polish households experience financial problems and exhibit both a low propensity to save, and low savings rates.
