Population over time
2 figuresUnion Center grew from 200 to 225 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.

| August 2018 | Flash Flood | Union Center | $28,700,000 | Runoff from heavy rain caused extensive flooding to occur in Elroy from the Baraboo River. Between 25 and 30 homes had to be evacuated. Numerous homes had water several inches to a few feet deep in the basements. Nine homes likely will have to be torn down. Damages in Elroy totaled nearly $6.5 million. The flooding along the Baraboo River also hit Wonewoc hard causing officials to evacuate the western half of the town. Dozens of homes had water in the basements with at least 4 of them suffering collapsed walls. Flooding along the Lemonweir River near Mauston caused Interstates 90/94 to be closed in both directions and washed out a rail line that caused the eastbound Amtrak Empire Builder to be stopped near Tomah. Passengers had to remain on the stopped train overnight until repairs to the rail line were completed. Flooding in Mauston damaged some homes with at least one a total loss when a basement wall collapsed. Flood waters from Webster Creek covered portions of State Highway 80 between New Lisbon and Elroy. State Highway 33 was under water in places between Union Center and Wonewoc because of flood waters from the Baraboo River. State Highway 82 was closed between Elroy and Mauston due to flood waters from Cleaver Creek. Portions of State Highway 58 south of Mauston was covered in flood waters from Onemile and Stewart Creeks. U.S. Highway 12 was closed between Mauston and Lyndon Station because of flooding on the Lemonweir River. County highways across the southern part of the county that were closed included: N, G, HH and FF. Numerous local and township roads were also closed. |

As the tornado moved east, it produced significant tree damage before weakening in intensity as it approached State Road 80, where it damaged a few more homes and several outbuildings. The tornado continued northeast, dealing intermittent tree and structural damage at EF-1 intensity along its path until it dissipated just west of Overgaard Road. |
| September 2018 | Flash Flood | Union Center | $230,000 | Several roads were closed with high water covering others across the southern portions of Juneau County.
