Severity ranking

ACAPS provides a weekly overview of current humanitarian priorities and recent events. Every Tuesday, we prioritise countries according to three categories of crisis: severe humanitarian crisis, humanitarian crisis, and situation of concern. Our weekly picks highlight those countries where developments in the last seven days have had an important impact on the humanitarian situation. Crisis analysis for all countries falling into these categories is updated at least weekly, using secondary data from a wide range of sources, including NGOs, international organisations, and media.

The categories are assigned on the basis of two indicators of the extent the current crisis:

  • the percentage of the population in need of assistance due to recent or protracted disasters;
  • the level of access to the affected population;

and three that together inform on a country’s underlying vulnerability to crisis:

  • the under-five mortality rate;
  • the Human Development Index (HDI) of the country; and
  • the number of protracted IDPs and refugees.

More information on our methodology for prioritisation can be found in the Methodology Brief.

Countries' sections

The overview page summarises the key facts about the crisis.

The crisis analysis goes into a little more detail regarding the humanitarian situation in the country, reflecting major developments over recent months. It includes multisectoral humanitarian data and information on recent political and security developments.

The country profile provides a baseline picture of conditions that may impact the humanitarian situation. Geographic, political, social, and economic data outline potential drivers, while sector-specific information gives pre-crisis data.

Outlook provide scenario or risk reports about potential future developments of humanitarian crises to inform contingency planning and preparedness. Unless otherwise specified, they normally look at potential evolutions over six months. For more on how ACAPS builds scenarios, see our Resources.

Among our special reports are:

  • Short Notes: a short update on an unfolding humanitarian situation where information is particularly scarce, or the country does not feature in our categorisation.
  • Briefing Notes: a humanitarian snapshot based on secondary data, providing essential information on context and immediate needs within 12-24 hours of a disaster.
  • Thematic Notes: longer, more focused reports analysing a specific topic, place or population group.


ACAPS carefully checks all the sources (primary and secondary data) it uses to undertake its analysis. For each source, our analysts make sure to respect the following methodological criteria:

  • Authenticity, accuracy, precision and reputation
  • Corroboration/consistency with other independent sources
  • Plausibility in context, logical

ACAPS has developed extensive technical material to improve analytical practices and skills, such as this technical brief: “Spoting dubious data”. Check our library section to find out more about it.
