Registered Joburg voters

Johannesburg's 2.4 million registered voters skew female across every age group without exception — a pattern that holds from the youngest cohort (18–19) through to those aged 80 and older. But the gap is most pronounced in the 30–39 bracket, where 301 926 women are registered compared with 269 504 men, a difference of over 32 000. The female majority of 53.4% therefore reflects a consistent structural pattern rather than a single outlier age group, giving women's voting preferences significant collective weight in any Johannesburg election.
