Hemlock, Ohio

Hemlock fell from 155 to 142 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 38 fires within 5 miles of Hemlock between 2012 and 2020, burning about 33 acres in total. None started naturally. 3 were 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:

• Buckingham
• Ludington
• Carrington
• Congo
• Drakes
• Sulphur Springs

Museums hold 96 specimens collected within 10 miles of Hemlock between 1890 and 1973: 69 Animalia, 14 Plantae, 9 Fungi, 4 Protozoa. 12 distinct Species records are shown. Collected by Coker W. C., Conan J. Taylor, Cooke, W. B.; Cooke, V. 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.

The National Weather Service names Hemlock in 3 storm reports between 2002 and 2013: 2 thunderstorm wind, 1 hail. 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.
