Population over time
2 figuresAlger fell from 1,200 to 837 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. 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 |

|---|---|---|---|---|
| December 2021 | Tornado (EF1) | Alger | $300,000 | The first sign of tornadic damage was observed at a residence just southwest of the intersection of State Routes 309 and 235, where part of the roof was lifted off of a barn and multiple softwood trees were snapped and blown in multiple directions.||The tornado then strengthened as it moved northeast, causing more substantial damage at a business and a two story residence, located on opposite sides of State Route 309, near the intersection with State Route 235. At the business, two outbuildings were completely destroyed and part of the roof of another building was lifted off, with debris splatter noted on multiple sides of this building. A metal sign was also damaged and a tractor trailer was overturned on its side.||At the two story home, the roof was completely lifted off, with parts of the roof thrown in multiple directions. Several windows were broken, most likely due to metal debris from the business across the road. Two outbuildings were completely destroyed. Debris from these outbuildings and debris from the home were blown at least 0.7 miles into the field to the northeast. Multiple trees also sustained significant damage. The tornado was strongest in this area, with maximum winds of up to 110 mph.||The tornado was likely still on the ground in the field to the northeast of State Route 235, however it showed signs of weakening as it crossed Township Road 55. On Township Road 55, shingles were removed from one home, while one outbuilding had partial roof uplift and another outbuilding was moved off cinder blocks. A few trees along a grove behind the home were also snapped.||Additional minor roof damage was observed on Township Road 64. This appears to be the end of the tornado as no further damage was noted to the northeast. |
