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.

Government

As of 2020, the members of the Hamilton Board of County Commissioners are Denise Driehaus, Stephanie Summerow Dumas, and Alicia Reece. Since 1963, the Board has employed an administrator to run the day-to-day operations of the county; the current administrator is Jeffrey Aluotto. Other elected officers include Dusty Rhodes (Auditor), Connie Pillich (Prosecutor), Charmaine McGuffey (Sheriff), Eric Beck (Engineer), Scott Crowley (Recorder), Jill Schiller (Treasurer), and Lakshmi Sammarco (Coroner). As of 2021, the elected Common Pleas Court include: Judge Jody Luebbers, Judge Lisa Allen, Judge Jennifer Branch, Judge Wende Cross, Judge Leslie Ghiz, Judge Robert Goering, Judge Tom Heekin, Judge Christian Jenkins, Judge Charles Kubicki, Judge Melba Marsh, Judge Terry Nestor, Judge Robert Ruehlman, Judge Nicole Sanders, Judge Megan Shanahan, Judge Alan Triggs, and Judge Christopher Wagner.

Portune's Chief of Staff, Victoria Parks, was appointed to serve the remainder of his term (through the November 2020 general election).
