Definitions The definitions and categories for disaggregation, specifically developed for the purpose of indicator 16.1.2 are based on international legal standards, existing statistical classifications and United Nations (UN) methodological standards on casualty recording.      International human rights law and international humanitarian law are two bodies of law that are complementary sources of standards in situations of armed conflict. These laws find their source in a series of international treaties, reinforced and complemented by customary international law. The International Classification of Crimes Statistics (ICCS) includes and distinguishes intentional homicides, killings directly related to armed conflicts, killings that amount to war crimes and other violations of the laws and customs applicable in international or non-international armed conflict. The ICCS is disseminated by the UN Office of Drugs and Crime (UNODC) and endorsed by both the UN Statistical Commission 4 and the UN Criminal Justice and Crime Prevention Commission in 2015.5 The World Health Organization (WHO) International Classification of Diseases (ICD-11), which includes a classification on war operations involving different weapons. International Committee of the Red Cross (ICRC) guidance on armed conflict and overview of weapons regulated by international human rights law. OHCHR Guidance on Casualty Recording, which provides methodological and operational guidance based on international law and drawing on OHCHR practice.6 The development of the approach has involved a series of consultation and coordination between institutions working on conflict-related issues to harmonize and build upon existing standards and methodologies, and to integrate their data into one collection that serves the purposes of this indicator. This involved consultations with a range of stakeholders, including national statistical offices, as part of the work of the Praia City Group on Governance Statistics created by the UN Statistical Commission, and the Global Alliance of National Human Rights Institutions (GANHRI). On 5-6 September 2017, a multi-stakeholders consultation brought together national statistical offices, national human rights institutions, civil society organisations (Peace Research Institute Oslo (PRIO), Small Arms Survey, and Human Rights Data Analysis Group (HRDAG)) and international and regional organizations and mechanisms (UNODC, United Nations Development Programme (UNDP), WHO, and the ICRC). The consultation validated a preliminary outline of the main features of the methodology put forward by OHCHR. Conflict The term ‘conflict’ used in the formulation recommended by the IAEG-SDG is understood as ‘armed conflict’ in reference to a terminology enshrined in International Humanitarian Law (IHL), the branch of international law which specifically focuses on armed conflicts. For the purpose of this indicator, identification of situations of armed conflict will be based on publically available assessments made by United Nations and other internationally mandated bodies and organizations (see section below on identifying armed conflict). 3
