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.
Only one state, Ohio, was in existence in what we know as the Midwest at that time. In 1803 The Northwest Territory was divided into the state of Ohio with the rest becoming the Indiana Territory.

The area in the Midwest that was part of the Louisiana Purchase in 1803 includes a significant portion of present-day Missouri, as well as parts of Iowa, North Dakota, South Dakota, Nebraska, and Kansas. This vast territory was acquired from France and greatly expanded the United States, facilitating westward expansion and settlement. The Purchase played a crucial role in shaping the geopolitical landscape of the United States.
Ohio was admitted into the Union on March 1, 1803 becoming the 17th state to join the Union. It is the only state that was admitted into the union during 1801-1803.
Between 1803 and 1860, the Midwest underwent significant changes, primarily due to westward expansion and the growth of agriculture. The region transformed from a largely uninhabited wilderness into a thriving agricultural hub, attracting settlers and immigrants drawn by the promise of fertile land. The introduction of new transportation systems, such as canals and railroads, facilitated trade and movement, further integrating the Midwest into the national economy. Additionally, this period saw the rise of cities and increased cultural diversity as various communities established themselves throughout the region.
We don't know what "this" is so we are unable to answer the question.
