Kuwait and Saudi Arabia both have high GDPs because of selling oil. Why is Kuwait's per capita GDP higher than that of Saudi Arabia?

Kuwait has a smaller population than Saudi Arabia.

Explanation:

The economy of Saudi Arabia is based on the oil and Kuwait has reserves of crude oil with it. Saudi Arabia manages to contribute more than 16% of the petroleum to the world while Kuwait contributes an approximation of 6%. The most interesting part of the two nations is the per capita GDP earned by them. Since Kuwait's population is smaller than Saudi Arabia therefore the per capita GDP of Kuwait is higher than that of Saudi Arabia. Saudi Arabia has adopted many measures to enhance and diversify its economy. It has been encouraging private sector to help in the growth of the economy.
