Putting America’s huge $20.5T economy into perspective by comparing US state GDPs to entire countries

The map above (click to enlarge) matches the economic output (Gross Domestic Product) for each US state (and the District of Columbia) in 2018 to a foreign country with a comparable nominal GDP last year, using data from the BEA for GDP by US state (average of Q2 and Q3 state GDP, since Q4 data aren’t yet available) and data for GDP by country from the International Monetary Fund. Like in past years, for each US state (and the District of Columbia), I’ve identified the country closest in economic size in 2018 (measured by nominal GDP) and those matching countries are displayed in the map above and in the table below. Obviously, in some cases, the closest match was a country that produced slightly more, or slightly less, economic output in 2018 than a given US state.

It’s pretty difficult to even comprehend how ridiculously large the US economy is, and the map above helps put America’s Gross Domestic Product (GDP) of $20.5 trillion ($20,500,000,000,000) in 2018 into perspective by comparing the economic size (GDP) of individual US states to the entire national output of other countries. For example:

America’s largest state economy is California, which produced nearly $3 trillion of economic output in 2018, more than the United Kingdom’s GDP last year of $2.8 trillion. Consider this: California has a labor force of 19.6 million compared to the labor force in the UK of 34 million (World Bank data here). Amazingly, it required a labor force 75% larger (and 14.5 million more people) in the UK to produce the same economic output last year as California! That’s a testament to the superior, world-class productivity of the American worker. Further, California as a separate country would have been the 5th largest economy in the world last year, ahead of the UK ($2.81 trillion), France ($2.79 trillion) and India ($2.61 trillion).
