In 2018, injuries resulted in more than:
Each of these cases represents a person whose life was impacted or taken by injury. The human costs of injury are both physical and emotional, and are felt by individuals, families, communities, and society as a whole.
Unintentional injuries account for the majority of injury cases:
Those aged 85 and older have the highest rate across all injury outcomes.

For all ages combined, falls was the leading cause of injury deaths, followed by suicide/self-harm, and transport incidents. Falls were the leading cause of hospitalizations, followed by transport incidents, suicide/self-harm, and unintentional poisoning.
The leading causes of injury vary when examined by age group. For example, for youth and young adults between ages 15 and 24, suicide/self-harm and transport incidents were top causes of death and hospitalization.
Potential Years of Life Lost (PYLL) emphasizes the loss of potential contribution younger individuals can make to society, and draws more attention to the causes of death that affect younger populations.
The total of 23,326 Potential Years of Life Lost (PYLL) due to injury emphasize the immense loss of life and potential when injuries kill people at a young age. Despite the 75+ age group having the highest death rate, PYLL places no value to these deaths. For all injuries, PYLL rate is highest in the 20-24 year old age group. The number and rate of deaths tend to be higher among older people because the risk of death increases with age. This can bias society to focus only on those causes of death that predominantly affect older populations. For unintentional injuries, the highest death rate was among those aged 75 and older. The exception was unintentional poisoning, where the death rate peaked in the 20-to-24 age group. For inflicted injuries, the death rate was highest among 20- to 24-year-olds.
PYLL can be used to quantify the human impact of all injury deaths. PYLL is calculated as the reference age minus the age at death. For the visualization below, the PYLL is based on a conservative life expectancy of age 75.

The Disability Adjusted Life Years (DALY) are the sum of years of life lost (YLL) due to premature death and years of healthy life lost due to disability (YLD). Unlike the calculation for Potential Years Life Lost (PYLL), where the same average life expectancy is applied to each case (e.g., 75 years of age), the YLL assumes that everyone who has died has also lost years of life, even if they have exceeded the average life expectancy.
DALY quantifies the human impact of deaths and disability. The DALY puts more emphasis on both the deaths and the disability occurring among younger age groups, as those who are younger have more years of healthy life to lose. This is particularly important to note when comparing causes that affect different age ranges. DALYs should not be used to compare causes of injury that are age-specific; for example, falls among older adults with self-harm among youth. In injury prevention, DALYs are used to determine effectiveness of programs and interventions, as well as resource allocation.
The DALYs are driven by unintentional injuries as they account for the majority of injury cases. In Atlantic Canada, in 2018, unintentional injuries accounted for 74% of injury deaths, 87% of injury hospitalizations, and 95% of ED visits.
