Population over time
2 figuresDecker fell from 249 to 199 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.
| Year | People | Change |

| May 2024 | Tornado (EF2) | Decker | $700,000 | The tornado with peak winds of 112 mph began near Decker where tree damage was found near the starting point. At the start, funnel clouds were jumping as most|of the damage was confined to the trees while houses remained|undamaged. The tornado quickly strengthened in producing low end|EF2 damage about a half mile east of Decker where a pole barn was|destroyed with debris found over a mile east of the original|damage location. In that same lot, a school bus was picked up and|moved about 20 yards away.||A sporadic damage path continued for about 2.5 miles northeast of|Decker with EF1 damage to mainly trees and one other small barn.|The sporadic damage path persisted through rural portions of|southern Knox County with EF0 tree and power line damage. About 3|miles southwest of Monroe City, the tornado hit another garage|structure, pushing in its bolted doors and causing the structure|to collapse. Debris from that structure was thrown about a mile|northeastward into a field, with drone footage capturing|circulations carved in the ground in that field. There were likely|a few circulations associated with the main tornado as additional|tree damage was found on the north side of this same property,|with no damage in between, leaving the house unaffected.||The tornado continued on its northeast path through southern Knox|County about a mile south of Monroe City, causing EF0 damage to|trees. The tornado lifted in rural portions of southeast Knox|County just prior to the Knox/Daviess County line. |
