For each of these seven dimensions, they identified the thresholds of severe deprivation, i.e. "those circumstances that are likely to have serious adverse consequences for the health, well-being and development of children" (Gordon et al, 2003: 31). Absolute child poverty was then measured as the condition of children suffering from two or more different types of severe deprivations. They found that over a third (37%) of children in the developing world lived in absolute poverty and over half (56%) suffered from at least one form of severe deprivation, using data from the Demographic and Health Surveys. Their work became part of the UNICEF Global Study on Child Poverty and Disparities. Using internationally recognized children's rights to inform the construction of child deprivation dimensions and counting the number of children suffering from several deprivations to produce the deprivation headcount rate became known as the Bristol method.
