CRC/C/15/Add.170 page 5 Data 23. The Committee is concerned at the absence of up-to-date and comprehensive data with regard to the implementation of the Convention and, in particular, that the data collected by individual ministries and other bodies are not integrated into a central data-collection mechanism. 24. Noting the State party’s efforts in this domain, the Committee recommends that the State party: (a) Strengthen its efforts to develop data collection systems and indicators consistent with the Convention and covering all children up to the ages of 18 years, with an emphasis on those who are particularly vulnerable, such as child victims of abuse, neglect or ill-treatment; children with disabilities; children who are not citizens of the State party; children belonging to distinct ethnic, religious, linguistic or cultural groups; children in conflict with the law; children who work; adopted children; and children living in the streets and rural areas; (b) Ensure that the data collected are disaggregated by, inter alia, age and gender, and include up-to-date information on budgetary allocations relevant to the Convention’s implementation; (c) Ensure that data collected by various ministries and other bodies are centralized and used in the formulation, evaluation and strengthening of policies and programmes for the effective implementation and monitoring of the Convention. Cooperation with NGOs 25. While noting the involvement of some NGOs in the preparation of the State party’s initial report, the Committee remains concerned that other relevant NGOs working on human rights, including children’s rights, and including NGOs from distinct ethnic, religious, linguistic and cultural groups were not involved in the process and that communication with part of the NGOs community has been insufficient. 26. The Committee recommends that the State party make every effort to further improve cooperation and coordination on a regular basis with NGOs and involve them in the Convention’s implementation, giving particular attention to NGOs working on behalf of the rights of children from distinct ethnic, religious, linguistic and cultural groups, such as the Roma. Dissemination of the Convention 27. Acknowledging the State party’s efforts in this regard, the Committee is concerned that knowledge and understanding of the Convention among children, professionals working with children, distinct ethnic, religious, linguistic or cultural groups and among the public in general is still insufficient. The Committee is concerned, in addition, that the Convention has not been translated into the languages of some sectors of the population, such as the Roma language.
