The county experienced rapid population growth during this time, with immigrants from the eastern United States and European countries moving in to take advantage of the fertile farming lands and economic opportunities. Additionally, the arrival of the railroad in the late 1800s further spurred development in the area, facilitating transportation and trade.

Livestock farming also played a crucial role, with cattle and hog production becoming important sectors. The county's agricultural output continued to expand, and improvements in technology and irrigation methods further boosted productivity.

Throughout its history, Adair County has faced challenges, including extreme weather events such as floods, tornadoes, and droughts. The Great Depression of the 1930s also impacted the county's economy, leading to significant population decline. However, the resilience and determination of the residents helped the area recover and prosper in the subsequent years.
