Made sense in 1789, when the entire country was more than 90% rural and total US population was 5,308,483. Today farm labor is less than 3% of the population of 325,000,000.
Today's 3d visualization, using recent data from the U.S. Bureau of Economic Analysis, shows the country's economy based on the relative economic output of each metropolitan area.
The results show how much cities and populous areas really contribute to a country's output, with an impressive 52% of total GDP created in America's 20 top metropolitan areas.
New York City's metropolitan area, which includes Newark and Jersey City, alone makes up $1.5 trillion of economic productivity. That's good for about 10% of the United States' total GDP.
The Greater Los Angeles area was the second largest individual contributor with $866 billion in GDP, and Chicago's metropolitan area adds $610 billion to the U.S. GDP. It turns out Texas is no slouch either, with the Houston and Dallas metro areas combining to produce over $1 trillion in tandem. www.visualcapitalist.com
