Implementation of the United Nations Convention on the Rights of the Child (crc) hinges on appropriate data collection to clarify actors' accountability and the impact of this on children. In spite of widespread ratification and revised legislation, most State Parties have not adequately implemented the crc. The evidence demonstrates that indicators can assist with implementing and monitoring human rights. We present an account of a decade of work conducted under the auspices of the UN Committee on the Rights of the Child, towards developing indicator sets which map the degree of rights implementation. The work started with the rights of young children, outlined in the Committee's General Comment No. 7. It will culminate in a comprehensive monitoring platform, called GlobalChild, to improve State Parties' accountability to children through pointing at crucial aspects of the process of compliance with the crc for which the State Party and its administration are accountable.
