By 2050, the world is likely to have changed drastically from what we know now, and the planet's economic and financial landscape will be no exception.

A report from professional services giant PwC looks at which economies around the world will be the biggest and most powerful in 33 years time. 

The report, titled "The long view: how will the global economic order change by 2050?" ranked 32 countries by their projected global gross domestic product by purchasing power parity.

PPP is used by macroeconomists to determine the economic productivity and standards of living among countries across a certain time period.

With the exception of the USA, many of the world's current powerhouse economies like Japan and Germany will have slipped down global rankings, replaced by countries such as India and Indonesia, which are currently emerging markets.
