|Top nations in engineering based on impact|
|Rank||Country||Papers||Citations||Citations per paper|
Both articles tabulated and citation counts to those articles are for the period indicated. Here our ranking in engineering journals is by citations per paper among nations that earned 25,000 citations or more to reveal weighted impact. 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 per cent for a field over a given period, based on total citations. In engineering, 96 nations are listed, meaning 192 were surveyed. Twenty-five nations collected at least 25,000 citations during the period. With the exception of the United States, the top-ranked nations in engineering are European; Denmark and Switzerland stand out despite relatively modest output. The next five nations (not listed above) were: Turkey (3.10 citations per paper), South Korea (2.79), China (2.78), India (2.62) and Russia (2.28).
