In 2014, Bahraini scientists published 155 articles in internationally cataloged journals, according to Thomson Reuters' Web of Science (Science Citation Index Expanded). This corresponds to 15 articles per million inhabitants, compared to a global average of 176 per million inhabitants in 2013. Scientific output has risen slowly from 93 articles in 2005 and remains modest. By 2014, only Mauritania and Palestine had a smaller output in this database among Arab states.
