However, in absolute terms the reduction was largest in the housing dimension, driven by falling rates of overcrowding. Most notably, these two countries increased the share of children who are not poor in any of the seven dimensions by substantially cutting the share of children who are poor in two or more dimensions at once, even if the share of children poor in just one dimension increased (as it did in Estonia).This suggests that in order to make progress towards Target 1.2 it is important to reduce the number of multiple dimensions a child is simultaneously deprived in. However, to avoid a 'mechanistic' approach to halving multidimensional poverty, improvements in all dimensions need to be encouraged. Very low work intensity is defined as below 20 per cent of "the ratio of the total number of months that all working-age household members have worked during the income reference year and the total number of months the same household members theoretically could have worked in the same period''15 Large families are households with three or more children under 16.
