Thunder Bay's 2023 open-data archive contains 2,045 reported incidents for the calendar year. This page looks at how those records break down by category, with the "Other" group (1,025) accounting for the largest share, followed by Assault (351) and Theft (234). The data window is the full year, not a 60-day map snapshot.
The full 2023 picture also includes Mischief (185), Break and enter (140), and Robbery (41). Within Other, Traffic & MVC (804) and Bylaw & Provincial (148) are the leading subcategories. This page uses Thunder Bay's two-year archive and reports incident counts as filed, not population-adjusted rates; because 2023 is the earliest archived year, there is no prior-year comparison on this page.
2023 is the earliest year in Thunder Bay's two-year archive, so there is no previous-year figure to calculate a year-over-year change. What stands out is the internal mix: Other (1,025) is much larger than Assault (351), and the Traffic & MVC subcategory (804) dominates that Other group. The remaining listed Other subcategories are Bylaw & Provincial (148), Other crime (39), and Drugs (34). The other named categories — Theft (234), Mischief (185), Break and enter (140), Robbery (41) — complete the 2023 distribution. These are reported incident counts, not population-based rates.
Between the two archived years, 2023 is the smaller one: 2,045 records versus 7,231 in 2024. The most striking feature of 2023 is how much weight sits in Other, led by Traffic & MVC at 804. Assault is the largest named crime category at 351 but trails Other by a wide margin. Bylaw & Provincial adds 148 to the Other group. A reader who looks only at named categories would miss the 1,025 incidents filed under Other in 2023.
Thunder Bay's 2023 open-data archive includes 2,045 reported incidents. This is the full calendar-year count used on this page, and it represents reported records rather than a population-adjusted rate. The count covers all categories in the archive, including Other, Assault, Theft, Mischief, Break and enter, and Robbery.
There is no year-over-year comparison for 2023 because no earlier year exists in Thunder Bay's two-year archive. The archive's other year, 2024, has 7,231 records, but that is the year after 2023, not a prior-year baseline. For a true trend direction, a longer series with counts before 2023 would be needed.
Other had the highest count in 2023, with 1,025 records. Within that group, Traffic & MVC accounted for 804 incidents and Bylaw & Provincial for 148. Assault was the largest named crime category at 351, followed by Theft at 234. This category highlight depends on how Thunder Bay's open-data source classifies traffic and bylaw records.
