In comparison with over 64% of output growth created within Emerging Markets, Developed Markets produced 18% contribution, Frontier Markets just 9%, and the Rest of the World 9%.

Whilst it must be remembered that it's far easier to produce impressive numbers from a low base (which has been the case for most Emerging Markets over the past thirty years), the enormous growth of China, India, South Korea (and others) in recent years means that this view is of less and less relevance today. Many economists have suggested over the past quarter century that (for example) China's extraordinary rise cannot continue at the same pace forever, which is necessarily true, sooner or later. But until Covid arrived, the slowdown in output growth in China had been modest, with growth that could only be described as rapid continuing virtually non-stop.

A further argument has also been directed at many Emerging Market countries, to the effect that the quality of their economic data is suspect, and therefore the growth rates quoted may be artificially high. The World Economics Data Quality Ratings do suggest that in some developing countries care should be taken in the interpretation of GDP and Population data, but the general quality of data has been improving, and some (for example, China again), has Population and GDP data now classed as A and B grade respectively.
