Children are more exposed to the effects of poverty than adults, therefore it is important to treat child poverty as a distinct topic from poverty in general. Furthermore, child poverty and adult poverty have different causes and effects, for example the consequences of child poverty usually persist in adulthood. For this reason, it is important to elaborate particular approaches and methods to understand and measure child poverty as well as its causes and effects. So far there is no agreement among researchers on the definition of child poverty and hence there are various measurement methods. In our paper we shortly introduce five types of child poverty approaches and their proposed methodology to measure it.
