CRC/C/GTM/CO/3-4 28. The Committee recommends that the State party develop a system of data collection and indicators consistent with the Convention and disaggregated by sex, age, rural and urban areas, ethnicity, disabilities, victims of violence and phase of life (particularly early childhood and adolescence). This system should cover all children up to the age of 18, with specific emphasis on those who are particularly vulnerable. It also encourages the State party to use these indicators and data in the formulation of policies and programmes for the effective implementation of the Convention. The Committee further recommends that the data collection be regularly updated, and made easily available to the general public. Dissemination, and awareness-raising 29.
