What is the biggest killer in South Africa?

Statistics South Africa has released a report on the top 10 leading causes of death in South Africa, based on all death notification forms maintained by the Department of Home Affairs.

The data covered all reported deaths logged in 2016, but also tracks data on deaths occurring during the period 1997 to 2015 to show trends in mortality in South Africa.

The results on mortality levels and trends indicate that mortality has continued to decline in the country.

The general trend of registered deaths processed by Stats SA indicated an increase in death occurrences from 1997 to 2006 – when the number of deaths peaked to 614,248 – and a decrease thereafter.

In 2016, a total of 456,612 deaths occurred, marking a decline of 3.5% from the 473,266 death occurrences for 2015 that have been updated for late registration.

Overall, mortality now occurs at older ages for both men and women in the country, which is an indication of decline in premature mortality, Stats SA said.

In 2016, male deaths peaked at age group 60-64 years (8.6%), while female deaths peaked at a much older age group (75−79 years  – 8.3%). Largely, there were more male deaths observed, and the sex ratio at death was 112 male deaths per 100 female deaths, the stats group said.

Causes of death

Overall, the cause of death in South Africa is largely due to what is categorised as natural causes, which account for 88.8% of all deaths that took place in 2016. The other 11.2% of deaths were non-natural causes.

For the first time since 1997, diseases of the circulatory system were the top ranking underlying main group of natural causes of death.

Generally, non-communicable diseases accounted for 57.4% of deaths in 2016 while communicable diseases were responsible for 31.3% of deaths in 2016, Stats SA said.

Tuberculosis maintained its rank as the leading cause of death in South Africa, albeit with declining proportions, while diabetes accounted for 5.5% – up marginally from previous data. These two big killers were followed by other forms of heart disease and cerebrovascular diseases, which both ranked third place at 5.1% each.

HIV moved up from the sixth position in 2014 and remained as the fifth biggest killer for both 2015 and 2016 deaths.

Non-natural causes

When it comes to non-natural causes of death, accidental injury is the biggest killer in this category, accounting for 66.5% of deaths. This is followed by assault (14.8%) and transport accidents (12.5%).

The ‘other’ category which accounts for the most causes of non-natural deaths here covers quite a broad range of incidents, ranging from falling, and coming into contact with venomous creatures, to things like being a victim of a natural disaster.
