Denison grew from 8,298 to 8,373 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.

June 1994Thunderstorm WindDenison$50,000A weak cold front dropped southeast into Iowa. The airmass was not as unstable as it had been over the previous days. Thunderstorms developed early in the day and took some of the punch out of the system. During the late afternoon hours, a line of thunderstorms developed ahead of the cold front. They were severe for a brief period of time. One tornado touched down in Plymouth County at Merrill. The tornado only made a brief touchdown and did not cause any significant damage. A short time later, a funnel cloud was seen near Moville in Woodbury County. Most of the damage by the storms was due to gusty winds. There were numerous reports of trees and power lines downed. The strongest winds were in Plymouth County. A 77 mph wind gust blew through Le Mars. The winds caused roof damage to one building there. Sixty to sixty five mph winds were reported at Remsen and Kingsley. High winds in Crawford County, at Denison, downed power lines and power poles. After that report, the storms weakened and were below severe levels through the rest of the evening.
