The "complexity of the economy" is determined by the diversity and uniqueness of products manufactured in a country. Among the most complex economies globally are Japan, South Korea, and several European nations, notably Germany.

The United States has a slightly lower economic complexity, similar to China and countries in Southern Europe. In comparison, our economy falls around the complexity level of nations in Latin America, being less complex than Brazil but more intricate than Peru. Surprisingly, our economy is even considered "more complex" than that of Australia!
