Jefferson, Ohio

Jefferson grew from 3,120 to 3,226 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.

Genealogical Gleanings from Ashtabula County Ohio, published 1920 names this settlement in its chapter on Jefferson Township. These are the passages that mention it, exactly as the scans read.

Taken for the Office of War Information and the Farm Security Administration, who photographed the country between 1935 and 1944. Works of United States government photographers, with no known restriction on use. Each opens its catalogue record.

Regional context, not property-specific evidence. The federal wildfire occurrence database lists 2 fires within 5 miles of Jefferson between 2020 and 2020, burning about 2 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:

• Anderson (historical)
• Bulah
• Denmark Center
• Gould
• Ollins Corners
• South Denmark

Regional context, not property-specific evidence. Museums hold 482 specimens collected within 10 miles of Jefferson between 1872 and 1975: 414 Animalia, 50 Plantae, 16 Fungi, 1 Unrecorded, 1 Chromista. 12 distinct Species records are shown. Collected by A. B. Fuller, A. Woolman, Ansley, G 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.
