The work intensity status of a household summarises the work status over the past year for all work age household members (aged 18 to 64). It is obtained by computing the ratio of worked months over workable months, averaged over all work age household members and subsequently divided into four categories (WI=0, 0<WI<0.5, 0.5<WI<1, WI=1). Characteristics of the child’s parents or carers refer to unemployment spells during the survey reference period, their country of birth and level of educational attainment.
