61. 2015 年，在最不发达国家的支出共计 102 亿美元。直到近期为止，国家一级支出总额中约有一半用于最不发达国家，高于全球官方发展援助的平均水平。在2014 年和 2015 年，这一比例降到 50%以下，在很大程度上是因为伊拉克和阿拉伯叙利亚共和国爆发人道主义危机，导致联合国在这两个国家以及周边受危机影响国家的支出上升。
61. Expenditures in the least developed countries totalled $10.2 billion in 2015. Until recently, approximately half of all country-level expenditures were spent in those countries, which is higher than the global ODA average. That share was below 50 per cent in both 2014 and 2015, owing in large part to the humanitarian crises in Iraq and the Syrian Arab Republic, which has led to an incre ase in United Nations expenditures in those two countries, as well as in neighbouring countries affected by those crises.
