CRC/C/15/Add.173 page 5 (c) To identify the amount and proportion of the budget spent on children at the national and local levels in order to evaluate the impact and effect of the expenditures on children. Data collection 16. The Committee, while acknowledging that the National Survey on Socio-Economic Characteristics (CASEN) takes place in Chile every two years, expresses its concern that the Survey is based mainly on surveys and does not include all the areas covered by the Convention. 17. The Committee recommends that the State party improve its system of data collection with a view to incorporating all the areas covered by the Convention. Such a system should cover all children below the age of 18 years, with specific emphasis on those who are particularly vulnerable. Dissemination 18. The Committee, while acknowledging that there have been efforts to disseminate the Convention during the process for the development of regional plans for children and to train professionals working with and for children in line with its previous recommendation (ibid, para. 18), nevertheless expresses its concern that these measures need to be strengthened, in particular in rural areas and among indigenous children. 19. The Committee recommends that the State party: (a) Increase its efforts to translate informative material into the main indigenous languages and disseminate it; (b) Develop more creative methods to promote the Convention, including through audiovisual aids such as picture books and posters, in particular at local level, and through media; (c) Continue and strengthen its efforts to provide adequate and systematic training and/or sensitization on children’s rights of professional groups working with and for children, such as judges, lawyers, law enforcement and health personnel, teachers and school administrators; (d) Debate and discuss the principles and provisions of the Convention with a view to integrating them into the curricula at all levels of the educational system; and (e) OHCHR.
