One of the strengths of the United States is its diverse economy, which comprises many industries that contribute to overall economic development and greater stability. Total U.S. economic output topped $16 trillion in 2015, and each state’s contribution to overall GDP was unique, both in terms of size and industrial composition.

For example, California, New York, and Texas each generated over $1 trillion in economic output in 2015. Combined, these three states accounted for 31% of the nation’s total economic output. Each state’s unique economic landscape is shaped by a range of factors, from legal regulations to the presence natural resources. For example, with the nation’s largest oil reserves, oil and gas extraction drives Texas’s economy. Meanwhile, since removing certain banking restrictions, credit intermediation drives the South Dakota economy
