Until recently, poverty was measured solely by individual or household income levels in relation to specific money-metric poverty lines. With the progress of research and the more frequent availability of adequate surveys, the concept of poverty expanded to take into account various aspects of living conditions. Consequently, a new concept of poverty has come to light, which includes various aspects of deprivation not limited to material dimensions. It has become known as multidimensional poverty and is measured by multidimensional poverty indices.
