This report (2018) compares current humanitarian crises based on their level of humanitarian access. Affected populations in more than 40 countries are not getting proper humanitarian assistance due to access constraints. Out of 44 countries included in the report, nearly half of them are currently facing critical humanitarian access constraints, with four countries (Eritrea, Syria, Venezuela, and Yemen) being considered as inaccessible. Moderate humanitarian access constraints are an issue in eight countries, and 15 face low humanitarian access constraints.
