Population over time
2 figuresWilton grew from 5,363 to 5,958 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.

| January 2023 | Flash Flood | Wilton | $134,000,000 | The Cosumnes River rose rapidly due to very heavy rains and already elevated levels from previous storms. Sacramento County OES confirmed the levee along the Cosumnes River breached in three locations overnight, causing flash flooding in the surrounding areas from Rancho Murieta to Wilton. SR 99 between Dillard Rd and Grantline Rd was flooded with numerous vehicles stuck in flood waters, requiring water rescues and was closed around midnight due to flooding. Flooding continued well into January. Sacramento County issued an evacuation warning overnight for the Wilton area, changed to a shelter-in-place warning a couple of hours later due to unsafe travel conditions with surrounding flooded areas. There were an estimated 3,200 to 3,500 people in the impacted area. There were three drownings attributed to the flooding, each entered as an individual event. |
| February 2017 | Flood | Wilton | - | Green Rd. in Wilton flooded due to levee over topping. Evacuations were ordered for low lying portions of Wilton and Point Pleasant. |
