Genoa, Ohio

Genoa fell from 2,336 to 2,232 between 2010 and 2020. These are the recorded population figures Wikidata holds for this place, reached through the Geographic Names Information System number this page is keyed on rather than by name, so they belong to this place and not to another of the same name. Most are census counts, but not all are: an early figure may be a founding or settlement estimate. The change column is computed, and is left blank where more than 20 years separate a figure from the one before it, because a gap that long is not a change between two counts.

Museums hold 733 specimens collected within 10 miles of Genoa between 1825 and 1975: 722 Animalia, 8 Plantae, 3 Fungi. 12 distinct Species records are shown. Collected by Al Szuch, Albiet, P., Berra, T. M. (Tim M.) & Class and others. Each is a physical object with a catalogue number, and each entry opens the museum's record. This is what was collected and kept, not a survey of what lives here - nothing can be concluded from a species being absent.
