Its original boundaries were those defined for the Symmes purchase contract in 1788: the Ohio River in the South, Great Miami River to the west, the Lesser Miami River to the east, and the Cayuhoga River to the North. Its area then included about one-eighth of Ohio, and had about 2,000 inhabitants (not including the remaining Native Americans). The county was greatly expanded in 1792 to include what is today the lower peninsula of Michigan. Since 1796, other counties were created from Hamilton, reducing the county to its present size.

Population

The county's highest population was recorded in the 1970 U.S. Census. Since then, the county has lost population at an average rate of three percent per decade. Although Hamilton County is experiencing a decline in birth rates and has higher death rates in older age groups (cohorts), out-migration of residents is the key factor in population loss. In the last decade, this population loss has been reversed, and it is estimated that both Hamilton County and the City of Cincinnati have grown their populations. The Cincinnati Metropolitan Statistical Area, over the last three decades has seen a 19 percent increase in population. Much of the region's growth has been through movement of Cincinnati and Hamilton County residents into neighboring counties.
