补充资料：苏丹人
| 苏丹人 Sudanese 非洲东北部苏丹的基本居民。按人种和语言，苏丹人大体可分为两大部分：北苏丹人和南苏丹人。北苏丹人约占全国人口的3／4，主要居住在苏丹北部到青尼罗河与白尼罗河的河间地区。大都信仰伊斯兰教，属逊尼派，不少人使用阿拉伯语。南苏丹人居住在苏丹南部草原沼泽地带，多数信仰万物有灵，盛行图腾崇拜，有80多种部落语言。北苏丹人中除阿拉伯人外，最重要的有受阿拉伯文化影响的努比亚人，青、白尼罗河之间的丰吉人，达尔富尔广阔地带的福拉人，尼罗河、阿特巴拉河与红海之间山区的贝扎人。北苏丹人大多从事农业，利用尼罗河水灌溉；有的以畜牧业为主，兼营农业。社会经济结构多受阿拉伯人影响。南苏丹人中主要有丁卡人、努埃尔人、希卢克人、邦戈人、阿赞德人等。他们主要从事畜牧业；有的地方经营少量农业，种植高粱、烟草等。苏丹人也是苏丹尼格罗人的简称。
