Recent trend

Year-over-year change is not available for the Latest day (2026-10-12) total of 1 incident, because the headline reflects a single occurrence day rather than a complete calendar year. For longer context, the multi-year archive lists 3,173 incidents in 2021, 3,709 in 2022, 4,376 in 2023, 4,396 in 2024, 4,155 in 2025 and 3,262 in 2026, with 2026 still incomplete and not directly comparable as an annual total. Separately, the full-archive comparison for complete years shows 2025 at 4,155 records versus 4,396 in 2024, down 5.5%, which describes calendar-year change and not the latest-day headline or the 60-day map window.

Category breakdown

The Latest day (2026-10-12) mix in Newmarket contains a single category. Assault is recorded with 1 incident, representing 100% of the day's total of 1 incident from York Regional Police open data. With only one record for 2026-10-12, there is no second or third category to compare for this latest occurrence day. This narrow daily breakdown differs from longer cumulative mixes where multiple offence types typically appear. Because police may still add reports for the latest day, the category count can rise if additional occurrences are published. The daily table should therefore be read as a snapshot of what was available for 2026-10-12, rather than as a portrait of Newmarket's usual offence distribution.

What this means

What stands out is how quiet the Latest day (2026-10-12) is: just 1 Assault in Newmarket Leslie Valley, against 636 incidents in the 60-day map window and 3,262 dated records in 2026 to date. A one-record day offers little basis for pattern reading. For wider context, the full-archive Other group includes 1,649 Threats and 1,059 Harassment records, which are person offences rather than physical assault, alongside the daily Assault count.

FAQ

How many crime incidents were reported in Newmarket on the latest day?
Newmarket recorded 1 incident for its latest reporting day, 2026-10-12.

Assault was the only category recorded for 2026-10-12 in Newmarket, with 1 incident accounting for 100% of that day's open-data mix.

How up to date is the Newmarket crime map?
The headline reflects the latest reporting day of 2026-10-12, which is also the maximum occurrence date in the current extract generated on 2026-10-13. Police may still add late reports for that day. Separately, the interactive map uses a rolling 60-day window that holds 636 incidents, so its total differs from the 1-incident single-day headline by design.
