When facing a disaster, people have different level of needs based on their location and type. Some communities are more affected than others, some are more resilient than others.

Response cannot reach all people in need, so needs must be prioritized, to know which areas and groups should be considered for response analysis and targeting. This process is called needs severity mapping. Coordination platforms first undertake sectoral severity mapping, later consolidated by OCHA in an intersectoral severity mapping. There is no standard methodology to prioritize needs, although OCHA may propose one at country level. Some common approaches are presented below:
