In 1998, the male to female ratio for registered suicide deaths was 4:1.

Error bars indicate 95% confidence intervals for rates.
  • Rates for males are highest at ages 20 to 39 years and males at ages 80 years and older.
  • A peak in the 65 to 69 year age group can be also seen (Figure 10). This profile was not seen in 1997 and is mainly due to a large increase in suicide deaths registered in SA for this age group. Occasional variations of this size may occur by chance.

Sections shaded in blue indicates most common method for specific age group and sections shaded in grey the second most common method.
Categories: Hanging: E953.0; Motor vehicle exhaust: E952.0, Firearm: E955.0-.4; Poisoning (solid, liquids): E950; Cutting/Piercing: E956; Other: remainder of E950-E959.
  • The proportion of suicide deaths by hanging increased between 1997 and 1998: in 1997 hanging formed 35.9% of registered suicide deaths in males, but in 1998 it comprised 47.1%.
  • In 1998, hanging was the leading method of suicide in males aged 10 to 84 years. In males aged 85 years or more, 'other specified' methods were the most common method. These were mostly due to drowning (six out of the eight cases).
  • Of suicides by males, about two-thirds of those aged between 10 and 24 years old hanged themselves, whereas about half of men aged 25 to 39 years committed suicide by hanging. For males between 40 and 84 years, hanging made up at least one-third of the suicide cases.
  • For males aged between 20 and 65 years, motor vehicle exhaust was the second most common method used to commit suicide.
  • Suicides by firearms declined from 1997 to 1998. In 1997 firearms comprised 14.4% of suicide deaths and in 1998 the proportion was 10.1%.

Table 3 shows equivalent data for female suicides registered in 1998.

  • Hanging was the commonest method for young women.
  • Poisoning by solid and liquid substances was the commonest method for middle-aged and older women.
