How this figure is calculated
Annual articles published in scientific and technical journals divided by Land area (sq. km), matched on country and year. Neither publisher issues this ratio as a series; it is computed here from both.
Annual articles published in scientific and technical journals ÷ Land area (sq. km)
Computed from
- Annual articles published in scientific and technical journals National Science Foundation Science and Engineering Indicators, via World Bank (2026) – processed by Our World in Data
- Land area FAOSTAT, Food and Agriculture Organization of the United Nations (FAO)
Statizoid computes this series; the underlying measurements belong to the publishers named above. The arithmetic is applied to every country and year where both inputs report, and nothing is estimated unless the page says so.
