In purchasing-power-parity (PPP) terms, the World Bank estimated the size of the global economy at approximately $180.0 trillion in 2025, measured in constant 2021 international dollars. Compared to 2015, where the GWP was estimated at around $133.0 trillion (constant 2021 international $), this is an increase of about 35.4%. Based on the same data, the GWP (PPP) grew at an average compounded annual growth rate of approximately 3.36% between 2000 and 2025, while the GWP (PPP) per capita grew by an average 2.18% per year during the same period.
Historically, according to DeLong's 1998 estimates, GWP growth was extremely slow for hundreds of thousands of years when all humans lived as hunter-gatherers. It then rose modestly with the Neolithic Revolution, and again from roughly 4000 BCE onwards when complex societies started to emerge. A period of relative stagnation or mild decline happened between around 1200 and the second half of the 14th century. After this, growth resumed at a somewhat higher and more stable rate from the 1400s through the 1600s. With the Industrial Revolution economic growth accelerated sharply reaching the high compound annual growth rates we experience today.
Recent growth
The table below gives recent values and year-on-year percentage changes for overall GWP growth from 2015 through 2025, according to the World Bank's world GDP (PPP) estimates in constant 2021 international dollars. Percentage-change is calculated year-on-year.
The following table shows the recent development of the GWP per capita, measured in constant 2021 international dollars. Percentage-change is calculated year-on-year.

Historical and prehistorical estimates
The following GWP data is based on world GDP (PPP) estimates in 2021 constant international dollars from the World Bank. Historical real GWP per capita (PPP) is sourced from the World Bank and measured in constant 2021 international dollars. "Trillion" in the table below refers to the short scale usage of the term, where 1 trillion = 1,000 billion = 1012.
In 1998, economic historian J. Bradford DeLong estimated the total GWP in 1990 U.S. dollars for the main years between one million years BCE and 2000 CE (shown in the table below). "Billion" in the table below refers to the short scale usage of the term, where 1 billion = 1,000 million = 109.
