First broadcast September 2005
If recent projections are on target, by the year 2050, the USA will no longer be the world's biggest economy, although it will still be in the top six.
Future global economic powers will include Brazil, Russia, India and China (the BRICs).
What will it be like to live in that world? What signs can we see in the BRIC countries that this future is already dawning?
Part One: Turning Tables
Is the US an ageing superpower? Are today's developing economies tomorrow's global powerhouses? The answer may well be yes.
Peter Day looks at the BRICs, the theory that Brazil, Russia, India and China will be major powers by the year 2050.
