The above chart shows that the proportion of children in poverty in workless families has decreased by a fifth in the last 20 years. During the same period of time, the proportion of children in poverty in families where at least one parent is working has remained consistent around the 20% mark. However after a third year of increases, the proportion of children in poverty in families where one parent is working has reached its highest level in almost two decades.
Poverty is measured as the proportion of children living in households with an after housing costs income below 60% of the contemporary median household income.
