Clay Center, Ohio

Clay Center fell from 276 to 262 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 959 specimens collected within 10 miles of Clay Center between 1825 and 1975: 942 Animalia, 11 Plantae, 6 Fungi. 12 distinct Species records are shown. Collected by AS Hazzard & party, Al Szuch, Albiet, P. 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.
