Israel spent 6.35% of its GDP on research and development in 2023, the highest share of any country in World Bank data. See the top 20 by R&D intensity, how absolute spending compares, and why the two rankings tell different stories.

South Korea runs 1,220 industrial robots per 10,000 manufacturing employees — the highest robot density on earth. See the IFR ranking, how the metric works, and why China's figure fell from 470 to 166.

5G reached about 55% of the world's population in 2025, per the ITU, but coverage, availability and speed are three different measurements. Germany reports 99.1% coverage while its 5G usage lags; South Korea's networks top speed tests. Here is what each ranking actually measures.
