The figures and findings reflected in the 2019 Humanitarian Needs Overview (HNO) represent the independent analysis of the United Nations (UN) and its humanitarian partners based on information available to them. While the HNO aims to provide consolidated humanitarian analysis and data to help inform joint strategic humanitarian planning, many of the figures provided throughout the document are estimates based on sometimes incomplete and partial data sets using the methodologies for collection that were available at the time. The Government of Syria has expressed its reservations over the data sources and methodology of assessments used to inform the HNO, as well as on a number of HNO findings.
