During the period from 1800 to 1850, the U.S. population expanded from 5 million to what figure?

During the period from 1800 to 1850, the U.S. population indeed grew significantly due to factors such as westward expansion, immigration, and high birth rates. The figure of 16 million reflects the rapid growth the nation experienced as it moved through the early phases of the 19th century, particularly following the War of 1812 and during the period of Manifest Destiny.

This increase can be attributed to notable events such as the Louisiana Purchase in 1803, which added vast territories to the United States, encouraging migration and settlement. Additionally, the economic opportunities that arose during this time attracted many immigrants, further accelerating population growth. The population reaching approximately 16 million by 1850 illustrates not only the demographic changes but also the broader historical context of expansionism and migration during this transformative period in American history.
