Hertfordshire County Council area. Every figure carries its own date.
What the recorded figures show, and what they cannot tell us.
Recorded crime and population
A larger population can mean more recorded offences even when the number of offences per resident falls. Read the total and the rate together.
A checked recorded-crime total and matching population rate for this exact council area are not available in this collection yet. The local mapped records below remain a separate measure.
Can we test the population theory over 30 years?
Only where the offence definitions, recording practices and area boundaries are comparable. Changes in reporting, police recording and the types of crime matter too. We do not join incompatible series or invent missing years.
No verified one-to-one current CSP/authority code relationship; aggregate or split geography requires review
2002/03: Series starts after April 2002 recording-standard introduction; not comparable to pre-2002 records.
2013/14: Offence grouping revision; source back-series retained. Recording practice changes also affect comparisons.
2017/18: Burglary classification changed; broad total retained but detailed groups need review.
2023/24: Burglary subcategories and recording-rule changes require interpretation review.
A comparable 30-year crime-and-population trend has not been established for this area.
For example, if offences rose by 10% while population rose by 20%, offences per resident would fall by about 8%. This is an illustration, not a finding about this area.
People commuting or visiting can also affect offences recorded in a place. The resident population is a useful common denominator, but does not count everyone present.
What could help? Follow the types and locations of repeated problems, check residents’ experiences, and assess the response. Area population totals do not identify who commits offences.
Reviewed figures: September 2024 to August 2026. This reviewed record covers fewer than 30 years, so the chart opens on all of it.

Data table and workings
UK Facts calculation: sum all 10 constituent district counts in the official county council footprint. Matching monthly extracts only; anti-social behaviour, transport police and unusable locations excluded. No average of district rates.
County council footprint only; separate unitary authorities are excluded.
Mapped records are approximate locations, not all crime or personal risk.
The table retains the full reviewed history when the chart is shortened. Preset ranges end at this measure’s latest published period. Yearly windows count published annual periods; monthly windows count months. Gaps are never filled with estimates.
