The Economist published their World in 2014
Here is their list of the top economies in the world (actually they published per capita GDP and per capita GDP PPP and population.) The total GDP and ranking was calculated from those numbers. China, India and Indonesia will have their GDP Purchasing power parity adjusted to be about 10-30% higher when the International Comparison of prices is published next month.
Several countries are close enough in nominal GDP that currency fluctuations will change their ranking.
The UK can pass France with minor currency changes.
Canada, Italy and Spain are close enough for currency changes to shift the nominal GDP ranking.
Brazil, Russia and India are close enough for currency shifts to change the ranking.
The European countries are not growing their population and will drift down the rankings of the next several years.
