54. 2015 年，国家一级支出为 215 亿美元，其中有 99 亿美元也即 46%用于非洲区域(见图十三)，比 2014 年增加了 10 亿美元。近年，西亚所占支出份额迅速增长，原因主要是伊拉克与阿拉伯叙利亚共和国境内人道主义危机不断。2015 年，该区域支出占国家一级支出的 25%，是三年前的两倍。与之相反，亚太区域和拉丁美洲及加勒比区域的支出规模与份额近年已经降低。
54. Of the $21.5 billion in expenditures at the country level in 2015, $9.9 billion, or 46 per cent, was spent in the Africa region (see figure XIII), representing an increase of $1 billion compared with 2014. The share of expenditures in the Western Asia region has increased rapidly in recent years, owing primarily to the continuing humanitarian crises in Iraq and the Syrian Arab Republic. In 2015, the region represented 25 per cent of country-level expenditures, more than double the share just three years ago. Conversely, both the volume and the share of expenditures in the Asia-Pacific region and the Latin America and Caribbean region have decreased in recent years.
