Obesity has been described by the World Health Organisation (WHO) as a “global ticking time-bomb with huge potential negative economic and health impacts, especially for the poor.”

In 2020, the World Bank released a report on the state of obesity around the globe. The report draws on data collected during a World Health Organisation study in 2016 about the prevalence of obesity among adults.

The key findings and insights from the new report, along with the complete obesity ranking from 2016, can be found below.
