It’s worth noting, though, that this doesn’t take into account the levels of inequality beyond comparing numbers of billionaires/non-billionaires.

The Gini coefficient is a popular method of measuring economic inequality, on a scale from 0 (total equality) to 1 (one person owns the entire nation’s wealth).

As of 2019, the US and China had Gini coefficients of 0.481 and 0.465 respectively, making them extremely similar in overall wealth inequality, which is extremely high for both nations.
