This figure can be refined still further with a measure called the poverty gap, which represents the average income of people living below the poverty line. For example, in both Belgium and the Czech Republic around 9% of people were living below the poverty line in the early 2010s. But in Belgium, their mean income was only around 19% below the poverty line while in the Czech Republic it was around 28%. This means, in effect, that poor people in the Czech Republic were generally poorer than those in Belgium.
