What it measures. How serious the crime recorded here is, not how much of it there is. Each recorded crime is weighted by the typical sentence for that kind of offence (the Office for National Statistics Crime Severity Score), so a robbery counts about 76 times a shoplifting offence. The total per resident is ranked against every neighbourhood. 10 means among the safest tenth.
Data. Street-level crime from data.police.uk, September 2016 to August 2026. Weights: ONS Crime Severity Score, year ending March 2025.

Up 17% in 5 years Recorded crimes in AL10, anti-social behaviour left out.
Crime severity: 1.3× the Welwyn Hatfield average (1.2× the England and Wales average). 97 recorded crimes per 1,000 residents a year.
"Violence and sexual offences" is 61% of the harm here. It is a broad police category: most of these crimes are assaults without injury, harassment and threats, often indoors between people who know each other, and only a small part are sexual or serious violent offences. Police data does not say which, so each one is weighted at the England and Wales average for the category, which can overstate a quiet residential area.
Anti-social behaviour: 32 incidents per 1,000 residents a year, not scored. Not a crime, so it is not part of the Safety score.
Distances are straight-line, not walking routes. Scores use fixed distance bands, so they do not depend on other districts. Higher is better.
What it measures. Recorded crimes per 1,000 residents a year, with burglary and robbery counting more than shoplifting, ranked against every neighbourhood. 10 means among the safest tenth.
