Population of Ohio

Analysis# Ohio Population Analysis Ohio's population of 11.8 million ranks it seventh nationally, though its 2.39% growth over the past decade reflects stagnation compared to its historical trajectory—particularly the 1960s peak growth period when the state experienced significantly stronger expansion. The state's modest recent growth rate suggests Ohio has lost competitive appeal relative to Sun Belt and Mountain West states that have absorbed population gains during this period. Despite ranking in the top seven, Ohio's below-average decadal growth indicates demographic headwinds that have persisted since the state's mid-century economic peak.
