Young people aged 16–24 account for one in five serious road casualties in Northern Ireland
There were 227 killed or seriously injured casualties aged 16–24 in 2025, up from 207 in 2024. That is the highest share of KSI casualties among the published age groups, but not proof of the highest per-journey risk.
People aged 16–24 accounted for 227 killed or seriously injured road casualties in Northern Ireland in 2025—20.2% of the KSI total and the largest share of any age group in the published figures. The count rose by 20 compared with 2024.
What changed between 2024 and 2025?
The PSNI/NISRA calendar-year statistics recorded 227 killed or seriously injured casualties aged 16–24 in 2025, compared with 207 in 2024. That is an increase of 20, or about 9.7%. The 2025 figure represented 20.2% of all KSI casualties, the highest proportion among the age groups reported.
Across Northern Ireland, 1,122 people were killed or seriously injured in 2025, including 56 fatalities and 1,066 people seriously injured. The overall KSI total increased by 11.3% compared with 2024. The figures place the age-group increase in the context of a wider rise in serious road harm.
Age-group totals are useful for understanding who is affected, but a higher count does not automatically mean a higher risk per trip. To compare underlying risk between age groups, analysts would need sound measures of exposure, such as journey numbers, distance travelled and the mix of road-user types.
A broad age group, not one kind of road user
The 16–24 category covers people with different levels of driving experience and many kinds of road use. It may include drivers, passengers, pedestrians, cyclists and motorcyclists, depending on the classification in the full statistical tables. Treating everyone in the age group as a driver would be inaccurate.
The headline total also does not reveal which types of injury account for the change. A rise in serious casualties could be distributed across several road-user groups, or be concentrated in one group or set of circumstances. The annual age total alone cannot answer that question.
It would be equally premature to attribute the rise to inexperience, night driving, speed or distraction without analysing the relevant records. Those are hypotheses that require evidence, not conclusions that follow from the age breakdown.
What the detailed data needs to answer
PureCar has archived collision, casualty and vehicle datasets intended to support deeper analysis of Northern Ireland road-safety patterns. The next step is to match casualty records to their parent collisions, validate age and road-user fields, and compare the 2024 and 2025 record distributions.
A strong follow-up would report how the 16–24 group breaks down by road-user type and injury severity, and whether the year-on-year increase is visible across those categories. It should provide the number of records included, explain missing classifications and make clear whether a statistic counts casualties or collisions.
The same analysis could examine a longer historical period. That requires consistent calendar-year totals and a check that categories have not changed in ways that undermine direct comparison. Even with a reliable time series, an increase in casualty count does not by itself reveal whether exposure or underlying risk changed.
From national totals to useful local evidence
A national age-group statistic cannot identify a particular junction, road or town as a cause of the increase. If PureCar develops a location-based follow-up, it should use verified coordinates or location descriptions, define geographic boundaries consistently and check how many records can be matched confidently.
Counts should not be turned into a “most dangerous roads for young drivers” list without a defensible method. A location may record many collisions because it carries a great deal of traffic; a fair risk comparison needs exposure data and comparable road conditions. Low counts also require care because a small difference can produce a large percentage change.
What drivers and passengers can take from the figures
The figures justify attention to serious road outcomes among young people, not stereotypes about an entire age group. The immediate safety advice is the same for every driver: stay focused, leave enough stopping distance, adjust speed to conditions, wear a seatbelt and never drive impaired. Passengers can also help by avoiding actions that distract the driver and speaking up when a journey is unsafe.
These are general precautions. The statistics do not prove that any one of them caused the year-on-year change or would have prevented a particular event.
The next PureCar question
The key question is whether the 20-casualty increase is concentrated in a particular road-user category, severity level or recorded circumstance. Linked records can help answer that more precisely than an annual age total, provided the joins and classifications are validated.
For now, the supported conclusion is clear: people aged 16–24 accounted for 227 killed or seriously injured casualties in 2025, representing 20.2% of the KSI total. The rise from 207 in 2024 deserves investigation, but it should not be misrepresented as proof of individual risk or of a particular cause.
Why the headline age band is only a starting point
An age group can be the largest contributor to the KSI total without having the highest risk for every type of journey. Different groups travel different distances, use different transport modes and spend different amounts of time on the road. The 16–24 group also includes people at substantially different stages of life and driving experience. A total should not be used to portray all young people as one type of road user.
The most useful next question is how the 227 casualties break down by road-user role and injury outcome. The analysis should distinguish drivers from passengers, pedestrians, cyclists and motorcyclists wherever those fields are available. It should then compare fatalities with serious injuries and check whether the 20-person rise between years appears across the group or is concentrated in a smaller category.
How to compare years fairly
A year-on-year comparison needs stable definitions. The same age boundaries, calendar dates and severity categories should be used in both years, and any changes in collection or coding should be documented. The counts should be reconciled with the official annual totals and the numbers of records with unknown age or road-user type should be stated.
Percentages need context, particularly where subgroup totals are small. The increase from 207 to 227 is 20 additional KSI casualties, or about 9.7%. That arithmetic is useful, but it does not show whether exposure increased, decreased or stayed the same. A claim about risk per driver or per journey would require suitable denominator data and a carefully designed comparison.
What location data could reveal
If reliable collision locations are available, PureCar could test whether the recorded increase appears across a wide geographic area or within particular road environments. Such an analysis should not rank towns or roads based on raw counts alone. A larger population or busier road network naturally provides more opportunities for incidents, and the location data may not be equally complete for every year.
Any map should state the period covered, what each marker represents and how duplicate casualty records from the same collision are handled. Where a location is uncertain, the analysis should not place it at a precise point and imply a level of accuracy the source does not provide. These safeguards matter particularly when the number of events at a local level is small.
Prevention without stereotypes
The figures justify examining serious injuries among young people, but they do not support generalisations about young drivers’ attitudes or behaviour. An effective response should be based on the circumstances actually documented in collision records and, where possible, evaluated against reliable evidence of exposure and outcomes.
General measures remain relevant to motorists of every age: concentration, safe speed, appropriate following distance, seatbelt use and never driving under the influence. Those measures should not be presented as the proven explanation for this year-on-year increase. For that, the data must show how the individual collisions occurred.
What would make this a stronger investigation?
A strong PureCar follow-up would publish the age-group totals by road-user role and severity, compare several consistent years and provide a clear methods note. It would include checks against official totals and disclose missing classifications. If exposure data is not available, it would say plainly that the analysis compares counts rather than risk.
That would turn a striking annual figure into a useful public resource. The published result is that 227 people aged 16–24 were killed or seriously injured in 2025. The investigative task is to establish which circumstances account for the change, if the linked records allow that conclusion, without allowing an age label to stand in for an explanation.
Methodology: The age-group totals and KSI share are from the 2025 PSNI/NISRA annual report. The numerical change and percentage difference are calculated from the published 2024 and 2025 totals. No causal explanation is inferred from age alone.
