What do New York City and Iran have in common? Their economies are about the same size – USA TODAY

World Economy

Some U.S. cities have such economic power that they dwarf some countries. Here's a list of the top 15 American cities that have economies bigger than those of some countries.

As an economic power, the United States is a country without equal. It is home to just 4.3% of the global population, yet it accounts for 23.9% of global economic output, according to data from the World Bank. 

Within the United States, economic power tends to be concentrated in major urban areas. For example, just 15 metropolitan areas account for over one-fifth of all economic activity in the country. The economies of these cities are so large that they rival the GDPs of most countries in the world. 

Using GDP data from the Bureau of Economic Analysis, 24/7 Wall St. identified the 15 metro areas with economies bigger than some countries’ economies. After selecting the 15 metropolitan areas with the largest economies, we matched each with a country with a similar GDP based on purchasing power parity – a measure which accounts for living expenses – using data from the World Bank. It is important to note that the GDP of the country listed is a close match with the corresponding city but is not always smaller. However, every metro area on this list has a larger economy than most countries in the world. 

Every city on this list has a relatively diverse and complex economy and is home to a range of industries. Still, these metro area economies are also often dominated by a single sector. In most of these metropolitan areas, finance, insurance, real estate, rental, and leasing is the largest industry. In other cases, manufacturing, or information, or professional business services ranks as the top industry. Often, the economic output of the largest industry in these places is greater than the GDP of many countries. These are America’s 25 thriving industries.

The economic strength of the metro areas on this list is partially attributable to the presence of major companies. Many of these metro areas are home to the headquarters of Fortune 500 companies that are critical to the economic vitality of their home city and surrounding areas.

Methodology:

To determine the U.S. metro areas with bigger economies than some countries, 24/7 Wall St. reviewed real GDP data for 384 metropolitan statistical areas and 194 countries. Data on real GDP for metropolitan areas in 2018 came from the Bureau of Economic Analysis and is in 2012 chained dollars. Data on real GDP by country in 2018 came from the World Bank is based on purchasing power parity and is in constant 2011 international dollars.

Nominal GDP uses market exchange rates to set the nation’s GDP — the value of all goods and services produced in a country. GDP on a PPP basis takes into account cost of living differences, and is favored by many economists for more accurately capturing quality of life. For developed countries, the differences between the two measures tend to be smaller. For developing economies, the differences tend to be larger, and most often, PPP is higher than nominal GDP.

We also reviewed economic output by industry in each metro area to identify the largest industry. GDP by industry at the metro area level came from the BEA and is for 2018.

Data on MSA population and median household income for 2018 came from the U.S. Census Bureau’s American Community Survey. Country population came from the World Bank. All data are for the most recent period available.
