Missouri's population currently stands at over 6.1 million residents, a significant increase from its early territorial days when it was sparsely populated. The state experienced substantial growth throughout the 19th and early 20th centuries, fueled by westward expansion, agricultural development, and industrialization in cities like St. Louis and Kansas City, peaking during periods of rapid American westward settlement and subsequent urban development. However, population growth has moderated in recent decades, with current trends characterized by modest overall increases; while metropolitan areas such as Kansas City, St. Louis, Springfield, and Columbia continue to see growth, often driven by suburban expansion and some in-migration, many rural counties face stagnation or decline due to out-migration and an aging populace. The state's demographics are also slowly diversifying, alongside a general trend of an aging population, reflecting a complex interplay of historical forces, internal migration patterns, and ongoing demographic shifts.
