South Africa has amongst the highest rates of homicide in the world, yet little is known about the contexts that shape fatal violence. One frequently feared context is robbery. We examine 68,801 robberies reported between 2003 and 2014 to predict risk factors for cases resulting in victim death. Robbery-homicide is rare in South Africa and its risk...

Chapter
South Africa has some of the highest alcohol consumption levels worldwide. It is a major risk factor for health-related harms, which are amplified through the intersection with poverty and informality of settlements in areas such as Khayelitsha, Cape Town. Access to alcohol in low-income townships is facilitated by structural, supply-side factors i...

Conference Paper
Background In 2009, the road traffic injury mortality rate (36.1 per 100 000 population) in South Africa was marginally lower than the rate for violence. Violence as a concerning public health problem receives considerably more attention from policy makers, and rates have halved between 1997 and 2012, while road traffic mortality rates remained con...
Conference Paper
Background At 109 per 100 000 population, South Africa’s injury mortality rate is approximately 1.6 times higher than the global rate of 66.2 per 100 000. Although homicide rates declined since the 1990’s, they remain high along with road traffic injury deaths. Two injury mortality surveys for 2009 and 2017 will be utilised to determine if there wa...

BACKGROUND:Global development goals increasingly rely on country-specific estimates for benchmarking a nation's progress. To meet this need, the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2016 estimated global, regional, national, and, for selected locations, subnational cause-specific mortality beginning in the year 1980. He...
