Road traffic injuries kill approximately 1.19 million people each year and are the leading cause of death among children and young adults aged 5-29. Pedestrians, cyclists, and motorcyclists account for over half of road traffic deaths globally. The burden falls disproportionately on low- and middle-income countries (LMICs), which have 60% of the world's vehicles but account for 93% of road fatalities. Africa has the highest road traffic death rate per capita, followed by Southeast Asia. Key risk factors include excessive speed, alcohol-impaired driving, non-use of seatbelts and helmets, distracted driving, and inadequate road infrastructure. Rapid motorisation in LMICs without corresponding investments in road safety infrastructure, traffic law enforcement, and emergency trauma care has created a growing epidemic. The economic cost of road injuries is estimated at 3% of GDP in most countries, with the highest proportional losses in those least able to absorb them. North America has among the world's highest health expenditure per capita, yet faces distinctive mortality challenges including the opioid epidemic, firearm violence, rising metabolic disease, and significant health disparities linked to race and income. In North America, unintentional injuries mortality is near global averages — a pattern shaped by the tension between world-leading medical capabilities and persistent disparities in healthcare access and social determinants of health.
The WHO Safe System approach addresses road safety through five pillars: safer roads and mobility, safer vehicles, safer road users, post-crash response, and safer speeds. Evidence-based interventions include speed limit enforcement, drink-driving legislation, mandatory seatbelt and helmet laws, vehicle safety standards, and separation of vulnerable road users from motorised traffic. Investment in pre-hospital and trauma care systems reduces case fatality. The UN Decade of Action for Road Safety 2021-2030 targets a 50% reduction in road deaths.
The mortality estimates presented on this page are derived from the Global Burden of Disease (GBD) study, produced by the Institute for Health Metrics and Evaluation (IHME). The GBD synthesizes data from vital registration systems, verbal autopsies, cancer registries, and surveillance networks across more than 200 countries and territories. Death rates are expressed per 100,000 population and are age-standardized, which adjusts for differences in age structure between populations so that comparisons across countries and over time reflect genuine differences in mortality risk rather than demographic composition.
The dataset typically covers the period from 1990 to 2023, although availability varies by country and cause. When interpreting the figures for unintentional injuries in North America, note that higher age-standardized rates indicate a greater mortality burden independent of whether a country's population is older or younger. Trends over time reveal whether public health interventions, economic development, and health system improvements have reduced or increased the toll of this condition in the region.
The cause-of-death categories used on this page follow the Global Burden of Disease cause hierarchy, a standardized classification that groups individual ICD-coded causes into clinically meaningful categories. The "share of deaths" metric shows what percentage of all deaths in a given country or region are attributed to unintentional injuries. A rising share does not necessarily mean more people are dying from this cause — it may reflect success in reducing competing causes of death. Always examine both absolute rates and shares for a complete picture of mortality patterns in North America.
