In 2014, Malawian scientists had the third-largest output in Southern Africa, in terms of articles cataloged in international journals. They published 322 articles in Thomson Reuters' Web of Science (Science Citation Index expanded) that year, almost triple the number in 2005 (116). Only South Africa (9,309) and the United Republic of Tanzania (770) published more in Southern Africa. Malawian scientists publish more in mainstream journals – relative to GDP – than any other country of similar population size. This is impressive, even if the country's publication density remains modest, with just 19 publications per million inhabitants cataloged in international journals in 2014. The average for sub-Saharan Africa is 20 publications per million inhabitants. Malawi was ranked 111st in the Global Innovation Index in 2020, up from 118th in 2019.
