Population over time
2 figuresSloan grew from 973 to 1,042 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.

| March 2019 | Flood | Sloan | $6,790,000 | Water inundated western areas of Moville during the evening of March 13, and continued through early on March 15. Iowa Highway 140 was closed north of Highway 20 at Moville due to flooding. At the height of the flooding, 29 sections of roadway were closed in Woodbury County, including two sections requiring long term repairs (Highway 982 near Holly Springs and County road L37 near Danbury). Other flooding resulted in extensive damage to public infrastructure. Gravel roads were hit especially hard as ice-plugged culverts resulted in large sections of roadway washing away. |
| June 2024 | Flood | Sloan | $4,130,000 | Rainfall amounts across Woodbury County from June 20-22 were generally 1.0 inch or less. Farther north and upstream, 6 to 10 inches fell across portions of northwest Iowa and southeast South Dakota. This rainfall resulted in record flooding along the Big Sioux, Little Sioux, and Floyd Rivers, and extensive overland flooding along the adjoining flood plains. ||Multiple communities were impacted by flood waters. At peak flooding, numerous swift water rescues were conducted. Approximately 1,000 people were evacuated from the Riverside Neighborhood of Sioux City, 500 people were evacuated from Correctionville, and 10 people were evacuated from Smithland. County-wide, there were approximately 300 homes that were damaged and 10 that were destroyed. ||Public infrastructure was also severely impacted. Approximately 50 roads and bridges were closed due to flood waters. The railroad bridge across the Big Sioux River to South Dakota collapsed. The Correctionville energy transfer station and sewage lift station failed, while the fire station and city hall flooded. The Smithland sewage lift station failed and the Sioux City Wastewater Treatment Plant was damaged. Preliminary damage assessments estimate the loss to public infrastructure to be 4.13 million dollars. |
