Population over time
3 figuresTroy grew from 1,222 to 26,305 between 1840 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.

This township is centrally located, bounded on the north by Washington, on the' east by the Miami River, on the south by Monroe and part of Union, and on the west by Newton ; organized about 1807, and named by the Commissioners appointed for that purpose, Concord, vying with the name given by Samuel Jones to Union. Traversed by excellent turnpikes in all directions, her eastern border laved by the Great Miami, along which runs the canal, drained by numerous streams ; rich and fertile soil, capable, within itself, of perpetual regeneration ^excellent building material, both stone and timber ; central market, in the seat of justice for her produce - she is truly in a happy position to enjoy all the facilities tending to prosperity in every direction. v

Among the early settlers, we may mention Aaron Tullis, who came from Kentucky by way of Dayton, in a wagon, with a family of boys, arriving here in 1805 ; William Barbee, who came about 1804 ; Reuben Shackelford, Alexander Telford. In 1806, John Peck, with eight children, Jacob, John, Joseph, Isaac, and four daughters, came from Kentucky and settled on Boone's place, one and a nau miles from Troy. Mr. Peck came in the winter, selected his land and bought loU acres/ with one acre cleared, for $100. It had a little log-cabin on it, one room 16x18. His stock having been brought from Kentucky, nearly all died the second year, losing eleven horses, besides sheep, hogs and cattle, only leaving him one mare, two or three cows and a few sheep. His land was of the best in the country, having four fine springs and good soil.

| When | Event | Place named | Harm | What the report says |
|---|---|---|---|---|
| June 2007 | Lightning | Troy | 3 hurt | A man and his two sons were standing underneath a tree when it was struck by lightning at the Troy Strawberry Festival. The three individuals suffered non life-threatening injuries. |

| January 2020 | Tornado (EF0) | Troy | $500,000 | The tornado touched down initially in the southwest portions of the city of Troy and moved northeast through the center of the city. It then crossed the Great Miami River before it weakened and lifted in the far northeast portions of the city.||Much of the damage was confined to trees and roofs, both residential and commercial, as the tornado moved through the city. To the west of the Great Miami River, damage was more intermittent and weak in comparison to areas east of the Great Miami River, where more concentrated and significant tree and roof damage was noted. In particular, areas near Troy High School and along and east of North Market Street saw the most concentrated and higher end structural damage to roofing material. This included the far eastern portions of the downtown area which saw several businesses lose all or portions of their roofs.||Damage was tornadic in nature, especially on the east side of the Great Miami River, where convergent tree damage was easily noted before the tornado rapidly weakened as it left the city. Damage along the path was consistent with wind speeds ranging from 65 to 80 mph, again with the highest wind speeds estimated on the east side of the Great Miami River. |
| July 2022 | Tornado (EF1) | Troy | $100,000 | The initial damage occurred near the intersection of Cheshire Road and Dorset Road, where several large tree limbs were downed. Damage became a little more concentrated near the intersection of Armand Drive and McKaig Avenue, where several large tree limbs and a few trees were downed. Tree damage also occurred at an apartment complex along Red Cedar Drive.||The most heavily concentrated area of damage occurred near Drury Lane and Ridge Avenue. Numerous very large, healthy trees were downed, with one trunk snapped at its base, and several other very large branches snapped not far off the ground. A couple of homes also had some minor roof damage. On West Simpson Street, just to|the east, a car was heavily damaged by a falling tree limb.||The damage path became narrower near Terrace Place, Market Street, and West Street. A bank sign was damaged and several more large trees and tree limbs were downed. In the neighborhood south of West Street, a few more homes had minor roof damage, with a fairly consistent area of tree damage observed as far southeast as Walker Street and Dakota Street.||Tree damage was also reported in other locations in Troy, such as Stanfield Road, West Ross Street, and Dakota Street. The rest of this damage is believed to have been caused by straight-line winds with speeds of 60 to 70 MPH. |
