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.

Ohio's geographic location has proven to be an asset for economic growth and expansion. Because Ohio links the Northeast to the Midwest, much cargo and business traffic passes through its borders along its well-developed highways. Ohio has the nation's 10th largest highway network and is within a one-day drive of 50% of North America's population and 70% of North America's manufacturing capacity. To the north, Lake Erie gives Ohio of coastline, which allows for numerous cargo ports. Ohio's southern border is defined by the Ohio River (with the border being at the 1792 low-water mark on the north side of the river), and much of the northern border is defined by Lake Erie. Ohio's neighbors are Pennsylvania to the east, Michigan to the northwest, Lake Erie to the north, Indiana to the west, Kentucky on the south, and West Virginia on the southeast. Ohio's borders were defined by metes and bounds in the Enabling Act of 1802 as follows:
