Articles are assigned to a category based on the journals in which they were published and Clarivate’s journal-to-category field definition scheme. Both articles tabulated and citation counts to those articles are for the period indicated. For articles with multiple authors from different nations, each nation receives full, not fractional, citation credit. Essential Science Indicators lists nations ranked in the top 50% for a field over a given period, based on total citations. In chemistry, 94 nations are listed, meaning 188 were surveyed. The average citation rate for field of chemistry is 11.19.
