This paper presents an analysis of child poverty and social exclusion in the UK, drawing on data from the 2012 Poverty and Social Exclusion Survey and is the final report on this element of the PSE project. It advances the measurement of child poverty by using three different measures: a child deprivation measure based on socially perceived necessities, the conventional income poverty measure (but with a more realistic equivalence scale) and a PSE measure which combines deprivation and low income. It finds the rates of child poverty for each measures are similar at 30%, 33% and 27% respectively. It also finds, from a new analysis of intra-household distribution, that child deprivation would be much higher if parents were not sacrificing their own living standards for the sake of their children. Analysing the characteristics of poor children it confirms that now a majority of poor children are living in households with someone in employment.
