Trend Information

  • The number of male and female KSIs have also dropped accordingly falling by 62% and 59% respectively.
  • In terms of the overall proportion by gender, approximately two thirds of KSIs each year are males ranging from 62% in 2015 to 69% in 2007.

Gender analysis of KSI casualties

In 2011-2020:

  • A higher proportion of male KSIs were aged 25 to 49 (39%) than that of females (30%) from this age group. A fifth of female KSIs were aged 65 or over (20%) which is almost twice the proportion of that for older males (11%).
  • Car drivers accounted for the largest proportion of KSIs for both males (37%) and females (41%).
  • Pedestrians were the second highest group for males (20%) while car passengers was second highest for females (28%).
  • Of the 1,734 pedestrians killed or seriously injured 1,076 were male (62%) and 658 were female (38%). The proportion differs considerably by age group ranging from 72% male for those aged 25 to 34 to just 48% male for those aged 65 and over.
  • Out of the 1,076 male pedestrian KSI casualties, 715 (66%) had responsibility for the collision assigned to the pedestrian. This is in comparison with 370 (56%) female pedestrians being responsible out of 658 female KSIs.
  • The proportions of males to females amongst car driver KSIs is approximately two-thirds male (63%) to one-third female (37%). The male proportions are highest amongst the younger age groups accounting for 67% of those aged 16 to 24 and 68% of those aged 25 to 34 whereas the proportions are 56% and 59% male for the 50 to 64 and 65 and over age groups respectively.
  • Car passengers are the only road user group to have more females (53%) killed or seriously injured than males (47%).
  • There were 72 motorcyclists killed on Northern Ireland’s roads within the last ten years with all of these being male riders. The overwhelming majority of the 1,010 motorcyclists killed or seriously injured between 2011 and 2020 were male (945 males and 65 females) which equates to 94%.
  • The number of pedal cyclist KSI casualties in the last 10 years were largely male. Of the 525 pedal cyclists killed or seriously injured 451 (86%) were male and 74 female (14%).
  • Proportionally, there were more males (40%) killed or seriously injured than females (31%) between 6pm and 6am while in contrast there were relatively more female KSI casualties (38%) between 10am and 4pm than males (31%).
  • The top two causation factors for male KSIs were impairment by alcohol/driver rider and excessive speeding (both with 12%). Heedless of traffic crossing carriageway (16%) and inattention or attention diverted (13%) were the top two causations for females.

Notes to editors: 

  1. Gender analysis of KSI casualties, 2011-2020 is part of a suite of problem profiles produced over the last few years by Analysis, Statistics and Research Branch (ASRB).
  2. The majority of the data within the report derives from the Police Service of Northern Ireland (PSNI) Road Traffic Collision Statistics, and is typically based on the period 1 January 2011 to 31 December 2020. The profile of these KSI casualties is then examined by age group and road user class overall, followed by a more detailed analysis by each road user group  followed by analysis of when and where KSI casualties occur, principal cause of collision, and who is deemed responsible.
  3. To provide context, data from the Northern Ireland Travel Survey (TSNI) have been provided along with mid-year population estimate to provide the distance travelled by different road users split by gender.
  4. The Department will use the information presented in this publication to support policy development. The report provides departmental officials with the current picture of KSI casualties, and provides evidence to allow them to consider the best ways to try to reduce casualty numbers.
