The bubble size displays the BPSM Power Score of the country in 2017, while the color presents negative (red) or positive (blue) power shifts since 2005. The darker the red, the more power lost the country concerned.
The Power Shift Rate (PSR) is the difference between the Power Scores of two points in time. This score illustrates whether a country lost or gained considering all indicators of our index. Please note that the updated dataset does not correspond to previous versions of the BPSM.
