Mount Orab, Ohio

Mount Orab grew from 3,664 to 4,347 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.

The federal wildfire occurrence database lists 1 fire within 5 miles of Mount Orab between 2012 and 2012, burning about 0 acres in total. None started naturally. None was recorded as arson. Distance is straight-line from the map coordinates, so a fire counted here may appear on a neighbouring settlement's page as well.

The most recent of them, most recent first, with the day each was reported and the service that recorded it.

Settlements close enough to share some of these fires:

• Andersonville
• Bardwell
• Bloom Rose (historical)
• Bodman
• Centerville

Museums hold 297 specimens collected within 10 miles of Mount Orab between 1886 and 1974: 165 Animalia, 106 Fungi, 24 Plantae, 2 Protozoa. 12 distinct Species records are shown. Collected by A JOHN, A. B. Seymour, A. Braun 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.
