How this figure is calculated
Scientific and technical journal articles 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.
Scientific and technical journal articles ÷ Land area (sq. km)
Computed from
- Scientific and technical journal articles Science and Engineering Indicators, National Science Foundation (NSF)
- 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.
