Where violent crime is reported most in Cardiff

Our safest areas in Cardiff post compared Castle ward — named the single highest-crime location in South Wales Police — against Cyncoed, one of the force’s three safest wards. Here we narrow that same comparison to one category: how much of each area’s crime was specifically violent?

What one month actually showed

Using the same four areas and the same July 2026 window as our other Cardiff posts, filtered to the police API’s violent-crime category only.

Where the reputation and the sample agree

Unlike some of the closer calls elsewhere in this series, this one lines up cleanly. Castle ward — officially the highest-crime location in the whole force — had both the highest raw count and the highest share of violent crime (54%). Cyncoed and Llandaff, the two quietest wards in our Cardiff coverage, had zero violent crime between them in the sample month; their only recorded incidents were a theft and a burglary. City Road sits where you’d expect a nightlife strip to sit: busier than the suburbs, quieter than the city centre, with violent crime making up roughly a third of its total.

Zero is still a small-sample number, not a guarantee — a different month could easily show a different picture for Cyncoed or Llandaff. But it’s a genuine result, not a truncation artefact: both areas’ entire crime count for the month was one incident each, and neither was violent.

See it for yourself

These open live with both postcodes already loaded, using twelve months of data rather than the single month above:

• Cardiff centre vs Cyncoed — the named-highest and named-safest wards, head to head.
• City Road vs Llandaff — the nightlife strip against the quiet suburb.

The limits of this data

This is recorded crime — what was reported and logged, not everything that happened — from one category, in one month, in small areas chosen to stay well under the police API’s reporting cap. It is not a verdict on any of these wards or the people who live there. For the fuller picture, see our Cardiff post, the safest areas in Cardiff post, and the police force crime rate ranking. And as always: none of this replaces calling 999 in an emergency.
