The paper investigates determinants of households ’poverty in Ukraine. We use Ukrainian Household Survey for three years - 2006, 2009 and 2010. Poverty in our paper is measured using an income and expenses approach, three different poverty lines are investigated. In this paper we aim to investigate the determinants of poverty among households, identify the most vulnerable and prone types of households, depending on a set of parameters - such as social, economic, demographic, and geographic. The main research outcome is that most welfare and poverty determinants change over time, as the economic situation changes, although such determinants as education and work experience are equally important in all periods.
