We have updated the indicator “Income per person (GDP/capita, PPP$ inflation adjusted)” to version 14. We added interpolations to all years, assuming a constant growth (instead of a constant increase in dollars). This gives a more realistic picture for fast growing economies with sparse data (such as the oil-rich gulf countries). We also made some historical revisions of China, UK, Cambodia, Lebanon, Malta and Greenland. You can view the new data here and the documentation here.
