A rank is drawn as its standing: the longer the bar, the nearer the top. Anything else is drawn against the larger of the two, and two values a hair apart are called level. Quality, excellence and the top-10% rate are explained in the methodology.

Who leads in each field?

Czechia stands higher in 9 of 26 fields, Portugal in 17. Portugal leads most in Chemical Engineering (#20 against #27); The Czechia leads most in Earth and Planetary Sciences (#25 against #32). Each bar is that side's standing among all countries ranked in the field: the full bar is first place.

Size is fractional works in the topics tagged with each word; colour is the word's share of the side's work against its share of the world's. Each word links to the topic it comes from most.

How has their output grown?

Portugal has out-published the Czechia every year since 2008, when it overtook it.

Fractional works per year.

Their share of all research

Growing output can still be a shrinking share, because all of science grows. Each line is a side as a percentage of every work published that year.

Fractional works over all fractional works that year. How the balance of science has shifted.

How much of it reaches the world top 10%

The share of each side's works, year by year, that reached the world's 10% most cited for their field and year. The average of all institutions is 10.0% (why not 10%).

still counting5%10%15%Portugal10.5% in 2025Czechia8.9% in 2025200020102020

A year with under 1% of the side's peak output is left out: a rate over a handful of papers says nothing. The latest years are still being cited.

Who holds more of the world's best institutions?

A country's average quality and the number of institutions it holds at the very top can disagree, and both are worth knowing. The counts are nested: an institution in the top 50 is also in the top 100.

Institutions ranked on research quality, 2022-now. Elite capacity counts a country's institutions by their worldwide rank, weighted so a place at #1 counts for more than one at #480.

Which publishes more research, Czechia or Portugal?

Portugal publishes 1.5× as much research as the Czechia in 2022-now (129k against 83k fractional works).

Whose research has more impact, Czechia or Portugal?

10.2% of Portugal's research reaches the world's top 10% most cited, against 8.5% for the Czechia.

Is Czechia or Portugal growing faster?

Output in 2022-25 was +4% against 2018-21 for Portugal, and -3% for the Czechia.

Which has more open access research, Czechia or Portugal?

58% of Portugal's research is free to read, against 44% of the Czechia's.

Which has more world-class institutions, Czechia or Portugal?

The Czechia holds 0 of the world's top 100 research institutions and Portugal 0; in the top 1,000 it is 5 against 7.

Which institutions lead in each country?

The highest-ranked institutions on each side on research quality, 2022-now. The percentage is each institution's own top-10% rate: the share of its works that are among the world's 10% most cited for their field and year. Every figure stands alone, so they do not add up to 100%.

The number is the rank inside the country. The track on each row is the top-10% rate; the tick is the average of all institutions, 10.0% (how it is set): teal above it, red below. The ranking is the quality score, which compares the rate with what each institution's own topics predict and adds a small reward for size, so the rates do not fall in order.
