As the indicators suggest, Ohio's population grew quite rapidly between 1900 and the mid-1960s, but has leveled off in recent years. The negative migration rates indicate that any change in population is primarily due to natural growth--i.e. and increase in birth rates coupled with a decrease in death rates in the state.
