How large is the world economy each year?

Question

Cifra · Accepted Answer

$105,000,000,000,000. World GDP is around $105 trillion a year, roughly $13,000 per person. The United States and China together account for about 43% of it. In 1960 the whole world economy was under $1.4 trillion in nominal terms. Multiply population by output per person. The world has eight billion people and the explanation gives per-capita output at around thirteen thousand dollars. Population times per-capita output gives a figure in the low hundreds of trillions, and this is the anchor every other economic question on this site scales against. The concentration is the structural fact: two countries account for around forty-three percent of the total. A global economy where two states produce nearly half of everything is far more concentrated than the population distribution would suggest, and it is why economic diplomacy is essentially bilateral. The historical comparison is what conveys the growth: the whole world economy was under one and a half trillion in nominal terms in 1960. Some of that is inflation, but a large part is real — global output per person has multiplied several times over within a lifetime, which is the single largest change in human material conditions ever recorded.
