This monthly headline figure reflects the last complete calendar month of published incident data for the municipality, offering transparent documentation of local law enforcement reporting for that specific timeframe.
While the primary monthly headline total accounts for 446 records in December 2025, the interactive map feed presents 3,043 incidents across a 60-day rolling window spanning from September 11, 2025 to December 10, 2025.

Recent trend
A formal year-over-year comparison is not available for December 2025 because the dataset's annual archive contains a single entry of 4,758 dated incidents for 2025. Without a complete prior annual dataset from earlier calendar years in the open-data feed, direct multi-year percentage comparisons cannot be calculated. The December 2025 count of 446 incidents stands as an individual monthly total within the 4,758 total records logged throughout 2025. Future open-data releases with multi-year archives will enable multi-period trajectory analysis across Cornwall.
