Population over time

2 figures

Uniopolis fell from 222 to 188 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.

History of Western Ohio and Auglaize County, with Illustrations and Biographical Sketches of Pioneers and Prominent Public Men, published 1905 names this settlement in its chapter on Union Township. These are the passages that mention it, exactly as the scans read.

The first religious society in Union township may be said tc have been formed by Rev. James B. Finley, a Methodist itinerant who preached in the homes of the people, particularly at Charles Lusk's house. The first house of worship was a log building,, located three miles southeast of Uniopolis, and known as Wesley Chapel. A church known as Poplar Hill Church was also a log building. Twenty years later both buildings were replaced by the present neat edifices.

Uniopolis was originally located in the southwest quarter of section 17, and was platted and organized by John Huffman, in September, 1837. Since its organization there have been additions as follows: No. 1, Samuel Focht's ; No. 2, John W. Howe's ; No. 3, Parlett and Stein's ; No. 4, George Blank's. This village was at a standstill until after the construction of the Ohio Southern Railroad. Since that time many buildings have been -erected and public improvements of a substantial character have been made. The population at the present time (1904) is about four hundred.
