Oman’s rise in Health and Wealth

Here is a very cute graph I did

A nice comparison over time of Oman’s rise in wealth and health

that shows the relative wealth and health of Oman and the UK.
The UK jigs along at the forefront of wealth and health compared to the world while Oman, until the 70s was low on both but then, sharply pulls up after 1970 with oil wealth and its much admired health services.
