Cynthiana, Ohio

The same ground, surveyed 71 years apart. Drag the handle to wipe between them. Both sheets are United States Geological Survey originals; neither has been altered.

1915 1986

Cynthiana fell from 68 to 57 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, and an estimate published within five years of a census is left out. 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.

Matched by testing this settlement's coordinate against the published boundary of every sheet in the United States Geological Survey's historical collection. Each opens the scanned sheet at the Survey.

Regional context, not property-specific evidence. The federal wildfire occurrence database lists 32 fires within 5 miles of Cynthiana between 2003 and 2020, burning about 104 acres in total. None started naturally. 1 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.

Regional context, not property-specific evidence. Museums hold 254 specimens collected within 10 miles of Cynthiana between 1926 and 1975: 235 Animalia, 9 Fungi, 7 Plantae, 2 Unrecorded, 1 Protozoa. 12 distinct Species records are shown. Collected by A VERWYST, A. Braun, A. Cronquist 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.

Regional context, not property-specific evidence. The federal mineral resources record lists 2 workings within 5 miles of Cynthiana: 2 past producers. None of them still produces. What was taken out: Limestone, General, Stone, Crushed/Broken. Distance is straight-line from the map coordinates, so a quarry counted here may appear on a neighbouring settlement's page as well.

Every working recorded in Pike County

Regional context, not property-specific evidence. The National Weather Service names Cynthiana in 8 storm reports between 1997 and 2025: 7 thunderstorm wind, 1 flood. No death or injury is recorded in these reports. Each account below is quoted exactly as the forecast office filed it, from the NOAA Storm Events Database, and each date opens the federal record of that event.

Matched on this settlement's Geographic Names Information System number rather than its name, so it cannot be a different place of the same name in another state.

This settlement is recorded in the Geographic Names Information System as feature 1061013.
