In 1803 how many states were in what is now the Midwest?

In 1803, the region that is now the Midwest was primarily part of the Northwest Territory, which included areas that would later become several states. At that time, Ohio was the only state formally admitted to the Union, having become a state in 1803. Other states in the Midwest, such as Indiana, Illinois, Michigan, Wisconsin, Minnesota, and Iowa, were not yet established as states but were part of the territory.
