Key Takeaways

Born during the 1970s oil crisis, the G7 emerged as the world economy's cool kids: large, mature, high-income economies dominating key global sectors.

Then, in the 2000s, BRICS showed up—a collection of economies from the “Global South”— vying for influence with their steadily growing economic might. Now they’re positioned as competitors to the G7.

Both groups are part of the G20—a collection of the largest economies in the world that make up 70% of the world economy in PPP-adjusted terms, and 85% at market exchange rates.

Why Use PPP-adjusted GDP?

Purchasing power parity accounts for the relative economic strength of middle and low income countries, where costs are lower than their high income counterparts.

As a result their PPP-adjusted GDP is a lot higher than the one based on exchange rates, and provides a somewhat-equal footing for comparisons.
