Search each box by a whole word from the name, then pick from the list. The comparison reads the indexed record of each — output, citations, depth of the cited record, how widely and how far the work is picked up, and how it ages.
It describes rather than ranks. No overall verdict is drawn: the two are usually of different sizes, most of the measures grow with size, and there is no single question a country comparison answers the way "where should this paper go" is answered for journals.
Reading the chart
The chart summarises six of the measures below. Every one of them is a ratio, so unlike the organisation charts elsewhere on the site it does not simply grow with the size of the country. It is still a profile rather than a scoreboard: further out means more of that thing.
Impact — average citations per article against the world average of the same publication year. Vs journals — how the articles did against the journals that carried them. Selectivity — the share of output placed in top-tier journals. Growth — the ten-year rate of growth in output, drawn as a growth factor so that a country whose output is shrinking still appears, nearer the centre. Ground gained — the country's share of world output now against its share ten years ago. Intensity — articles per billion dollars of research spending, the nearest thing here to productivity. Absent unless both countries report research spending.
