Type 1 diabetes

Facts about type 1 diabetes

  • There is currently no cure for T1D, and its exact cause isn’t known.1
  • T1D is a chronic auto-immune condition in which the pancreas produces little or no insulin by itself.2
  • It’s been found that 90% of people living with T1D have no family history of the condition, but having a family history does put people at higher risk of developing T1D.3
  • T1D was once known as juvenile diabetes or insulin-dependent diabetes.4 (This is where JDRF gets its name, as JDRF is an acronym for Juvenile Diabetes Research Foundation.)


Type 1 diabetes statistics in Australia

  • The T1D community in Australia is made up of 130,000+ people.5
  • Every year, over 2900 children and adults are newly diagnosed with T1D.6
  • About eight people are diagnosed with T1D every day in Australia, and half are adults.7
  • Currently, T1D accounts for 9% of all diabetes in Australia.8
  • There’s a similar incidence rate of T1D among Indigenous and non-Indigenous Australians.9


Facts about type 1 diabetes in children

  • T1D is one of the most common chronic childhood conditions.10
  • For kids, the symptoms usually come on very quickly and are quite obvious, while in adults, the onset is slower.11
  • While T1D can develop at any age, it’s more commonly diagnosed in younger people. More than 50% of those diagnosed with T1D in Australia are aged under 25.12
  • The peak age group of T1D diagnosis is 10–14 years old – more than 2 times the rate at 20–24 years old.13
  • There’s a fairly even split between girls and boys who are diagnosed with T1D.14
  • As of 2018, more than two-thirds (67%) of children and young adults living with T1D were aged 15–24 years.15


If you’re new to a T1D diagnosis for yourself or someone you love, it’s normal to feel overwhelmed with information. But please remember that you’re not alone, and there’s a huge support network available to you.
