According to the Australian Bureau of Statistics, around 63,300 Australians aged over 16 – 0.3% of the overall population – know they were born with variations of sex characteristics. This means their bodies don’t fit medical norms about how female or male bodies should look or function.
But the actual number is thought to be much higher, as many people don’t know about their physical difference or medical history, or don’t receive a clinical diagnosis. Some people learn their medical history later in life. Some never do.
