Encourages all States to strengthen their national statistical capacities and, as far as possible, to use statistics disaggregated by, inter alia, age, gender and other relevant factors that may lead to disparities, including in the area of juvenile justice and on children in detention, and other statistical indicators at the national, subregional, regional and international levels to develop and assess social policies and programmes so that economic and social resources are used efficiently and effectively for the full realization of the rights of the child; 7. Calls upon all States to end impunity for perpetrators of crimes committed against children, recognizing in this regard the contribution of the establishment of the International Criminal Court as a way to prevent violations of human rights and international humanitarian law, in particular when children are victims of serious crimes, including the crime of genocide, crimes against humanity and war crimes, and to bring perpetrators of such crimes to justice, and not to grant amnesties for these crimes and to strengthen international cooperation towards the goal of ending impunity; 8.
