Indeed, the countries with the highest fertility rates are predominantly Muslim, led by Niger, with 7.6 live births per woman, followed by Somalia with 6.7, and Chad with 6.. According to the Pew Research Center, the number of Muslims in the world will nearly equal the number of Christians by 2070, and Islam will become the world’s largest religion by 2100.
上述增长将主要发生在穆斯林世界，包括中东和萨赫勒地区。事实上，生育率名列前茅的国家大多以穆斯林为主，其中最高的是尼日尔，每名妇女产下7.6名活婴。紧随其后的是索马的6.7名和乍得的6名。皮尤研究中心数据显示，全球穆斯林人数将在2070年接近基督徒的人数，而2100年伊斯兰教的规模将成为世界第一。
