CRC/C/ARG/CO/3-4 provinces remain, and are as extreme as 500 per cent between the poorest and richest provinces. 22. The Committee recommends that the State party, in the light of articles 3 and 4 of the Convention, take all appropriate measures, to the maximum extent of available resources, to ensure that sufficient budgetary allocation is provided for services for children and that particular attention is paid to the protection of the rights of children from disadvantaged provinces and groups, including indigenous children and children living in poverty. In particular and in line with the Committee’s recommendations resulting from its day of general discussion on “Resources for the rights of the child responsibility of States”, the Committee encourages the State party: (a) To continue increasing the level of social investment while maintaining its sustainability; (b) To protect children’s and social budgets from any external or internal instability, such as situations of economic crisis, natural disasters or other emergencies, in order to maintain the sustainability of investments; (c) To ensure the expansion of and equitable allocation to disadvantaged provinces and groups in order to address disparities and, in particular, consider migrant children and children in alternative care (both in foster care and in other alternative care) as recipients of the Universal Family Allowance per Child; (d) To define strategic budgetary lines for those situations that may require affirmative social measures (such as birth registration, chronic malnutrition, violence against children, children without parental care, indigenous and migrant children, etc.); (e) To ensure proper accountability by local authorities in an open and transparent way that enables participation by communities and children, harmonized allocation and monitoring of resources; (f) To continue seeking technical assistance from UNICEF and other international organizations, as appropriate. Data collection 23. The Committee welcomes the establishment of the National Registry on Comprehensive Protection of Children and Adolescents (Decree 2044/2009), as well as the Directorate for Institutional Management and Development, which is in charge of the monitoring and evaluation of programmes for children, adolescents and the family. It also notes the commitment (Acta de Compromiso) with the provinces to build an integrated system of information on policies for children and adolescents. The Committee, however, remains concerned that the absence of a systematic approach to data collection and analysis in coordination with the National Institute of Statistics and Censuses continues to impede the availability of transparent and reliable data, disaggregated by provinces and municipalities as well as by other relevant variables such as gender, age, children with disabilities and indigenous children. 24. The Committee urges the State party to take the necessary steps to ensure that plans for the integral system of information on policies for children and adolescents are implemented and coordinated with the National Institute of Statistics and Censuses, covering all aspects of the Convention. The State party should ensure that information collected through this integral system contains transparent, reliable and comparable data on all rights, disaggregated by provincial and municipal location, gender, age and income, in order to enable policy and programme decision-making and to ensure public knowledge of progress made and gaps in its implementation. 5
