Since China's transition to a market-based economy through privatisation and deregulation, the country has seen its ranking increase from ninth in 1978 to second to only the United States in 2016 as economic growth accelerated and its share of global nominal GDP surged from 2 % in 1980 to 15 % in 2016. India has also experienced a similar economic boom since the implementation of economic liberalisation in the early 1990s. When supranational entities are included, the European Union is the second largest economy in the world. It was the largest from 2004, when ten countries joined the union, to 2014, after which it was surpassed by the United States.

Who had the worlds largest economy in 2014? OK. Let's think. My stream of consciousness: <ibo> Ọ bụ ezie na ọkwa nke akụ na ụba mba agbanweela nke ukwuu ka oge na-aga, United States anọgidewo na-anọ n'ọkwá ya kemgbe oge Gilded Age, oge nke akụ na ụba ya hụrụ mgbasawanye ngwa ngwa, na-akarị Alaeze Ukwu Britain na usoro ndị eze Qing na mkpokọta mmepụta.
