The share of world GDP of TPP members is about 54%

Is the GDP of all the 12 TPP members combined really 60% of the world’s total? My calculation based on the most recent World Bank’s GDP data (in current $US) for 2014 suggests it was 53.7%, or 54%, that is a 10% smaller than 60%.

Please note that there is no data for New Zealand so its 2013 figure plus 5% was used as an estimate.

There are some other countries whose data are not available for 2014 too, but they, including Taiwan, are mostly small economies.

PS: I haven't calculate the trade shares.
