CCPR/C/15/Add.68 page 3 11. The Committee is concerned at the insufficient measures adopted to ensure effective coordination between different governmental departments competent in areas covered by the Convention as well as between the central and local authorities. 12. The Committee is deeply concerned about the insufficiency of measures to collect disaggregated statistical data and other information on the situation of children, especially those belonging to the most vulnerable groups. This type of information is lacking in particular with respect to girl children, children living and/or working in the streets, disabled children, children living in rural areas and indigenous children. The absence of qualitative and quantitative information on the status of children renders deficient the systematic monitoring of the implementation of the Convention. 13. The Committee is of the view that insufficient measures have been adopted to promote widespread awareness of the principles and provisions of the Convention among adults and children alike, particularly those belonging to indigenous populations. The Committee is concerned at the lack of adequate and systematic training provided to professional groups working for and with children, including judges, lawyers, law enforcement personnel, health professionals, teachers, social workers, personnel working in child care institutions for children, police officers and officials of the central and local administrations. 14. The Committee expresses its concern at the insufficient budget allocation at all levels for social expenditures, in particular in favour of children belonging to the most disadvantaged groups of the population. The Committee notes with great concern the trend towards the perpetuation of poverty amongst marginalized groups of children in Panama, where 25 per cent of families live in poverty and 20 per cent live in extreme poverty. Despite the efforts made by the State party in the health and housing sectors, the situation is still precarious. 15. Particular concern is expressed by the Committee at the insufficient measures undertaken to ensure the effective implementation of the general principles (arts. 2, 3, 6 and 12) of the Convention on the Rights of the Child in practice, especially with regard to the girl child and children belonging to indigenous groups and to poor families. The Committee is deeply concerned about the high incidence of abandoned children and by the fact that approximately 20 per cent of the children born each year are to adolescent mothers. 16. The Committee is concerned by the persistence of violence against children within the family, including the use of corporal punishment. In the light of article 17 of the Convention, the Committee is also concerned about the need for further measures to protect children from media information and material injurious to their well-being. 17. In the light of article 2 of the Convention, the Committee is concerned about the insufficient measures, including of a legislative nature, taken by the authorities to regulate adoption adequately and to prevent and combat abuses, such as the trafficking of children.
