Answer:
Ohio's population tripled between 1820 and 1840 but only increased by about 50 percent from 1840 to 1860.
Although Ohio had ports of entry on Lake Erie, no passenger lists for ships are available. The majority of the immigrants arrived through eastern ports (New York, Boston, Philadelphia, Baltimore) and New Orleans. The library has records for each of these ports from 1820 to about 1920 or later. Philadelphia records start in 1800. Records of persons coming from Canada to the United States were not recorded until 1895. For records after 1895, see "Canadian Border Crossings, 1895-1954" in the the United States Emigration and Immigration.
