In 2013, Coram International was contracted to conduct an extensive, multi-country assessment of the impact of universal birth registration at the micro level (for individual children and youth) and at the macro level (for the State). Thematically, the project focused upon the impact of birth registration in the areas of child labour, early marriage, juvenile justice and parental responsibility. This project included an extensive literature review of existing data and reports relating to the impact and potential benefits of birth registration, as well as qualitative primary research in four selected Plan programme countries: India, Kenya, Sierra Leone and Vietnam. The research was conducted in partnership with the International Observatory on Statelessness which was carrying out a complimentary quantitative analysis of existing data sets. Coram International was responsible for incorporating this quantitative analysis into a final report, which provided case studies from the selected Plan programme countries, as well as overarching findings and recommendations relating to birth registration.
