Ohio
From just over 45,000 residents in 1800, Ohio's population grew at rates of over 10% per decade (except for the 1940 census) until the 1970 census, which recorded just over 10.65 million Ohioans. Growth then slowed for the next four decades. The United States Census Bureau estimates that the population of Ohio was 11,689,442 on July 1, 2018, a 1.33% increase since the 2010 United States Census. Ohio's population growth lags that of the entire United States, and Caucasians are found in a greater density than the United States average. , Ohio's center of population is located in Morrow County, in the county seat of Mount Gilead. This is approximately south and west of Ohio's population center in 1990.
