Emerging economies showed some of the largest increases in research output in 2018, according to estimates from the publishing-services company

 Clarivate Analytics. Egypt and Pakistan topped the list in percentage terms, with rises of 21% and 15.9%, respectively.

China’s publications rose by about 15%, and India, Brazil, Mexico and Iran all saw their output grow by more than 8% compared with 2017.

Globally, research output rose by around 5% in 2018, to an estimated 1,620,731 papers listed in a vast science-citation database Web of Science, the highest ever.

The estimates were compiled for Nature by Clarivate, which owns Web of Science, and the analysis focused on 40 countries that have at least 10,000 papers in the database. The whole-year projections are based on the number of research and review papers published between January and August, because there is a time lag between papers being published and them appearing in the database.
