According to the latest U.S. census data, Missouri’s population has consistently increased over the past two decades, reaching over 6.1 million people in 2021.
Nevertheless, the growth is not uniform across all counties in the state. Some counties have encountered notable decreases in population, pointing to diverse economic, social, and environmental obstacles.
Examining the shift from the 2010 census to the 2020 census, here are the top five Missouri counties experiencing the most rapid population decline:

Holt County

Possible Factors That Contribute to the Population Decline
Lack of Economic Opportunities
Numerous counties are predominantly rural and depend on agriculture, manufacturing, or mining as their primary industries. Nevertheless, these sectors have encountered difficulties like low commodity prices, automation, outsourcing, and environmental regulations, resulting in job cuts and lower incomes.
Consequently, a significant number of residents have relocated to urban areas or other states in pursuit of improved job opportunities.

Aging and Outmigration of Young People
Another reason for the decrease in population in these counties is the combination of aging residents and the departure of young people. These areas often have an older population than the state average, signaling lower birth rates and higher mortality rates.
Furthermore, a significant number of young individuals who finish high school or college choose to relocate for further education, career opportunities, or exposure to different cultures.
Unfortunately, many of them do not come back, leading to an imbalance in demographics and a loss of valuable human resources.
