There were an estimated 265 births of babies with Down syndrome per year between 2016 and 2020
Down syndrome is a genetic disorder where individuals inherit an extra copy of chromosome 21 from their parents. It is not an illness or disease, but people with Down syndrome do experience a range of specific health challenges and will have some level of cognitive impairment, from mild to severe. It is the most commonly occurring chromosomal condition and the most common genetic cause of intellectual disability.
The average life expectancy for people with Down syndrome in Australia is 60 years or more, a dramatic increase over the past 50 years. This is due to improved health screening and better access to support. The National Disability Insurance Scheme (NDIS) helps people with Down syndrome to access the support they need to live longer and healthier lives.
While there is no national data collection on the number of people with Down syndrome in Australia, it is estimated that between 2016 and 2020, there were 265 births of babies with Down syndrome per year. This equates to around 1 in every 1,158 babies born in Australia during this period. This estimate is based on data from Western Australia and is supported by recent NDIS participant data.
The number of births of babies with Down syndrome is likely to increase as the NDIS expands across Australia and more support becomes available. It is important to note that not all people with Down syndrome will be NDIS participants, and the actual number of people with Down syndrome in Australia may be higher than estimated.

There are between 13,000 and 15,000 individuals with Down syndrome in Australia as of 2019
Down syndrome is a genetic disorder where individuals inherit an extra chromosome from one of their parents. Most people with Down syndrome are born with three copies of chromosome 21 in every cell, whereas most people typically have two. As of 2019, there were an estimated 13,000 to 15,000 individuals with Down syndrome in Australia. This estimate is based on data from Western Australia, extrapolated to the broader Australian population.
The prevalence of Down syndrome in Australia translates to approximately 5.14 cases per 10,000 people. This rate is comparable to that of other countries, such as the United Kingdom. While there is no comprehensive national data collection on the number of people with Down syndrome in Australia, estimates suggest that between 2016 and 2020, there were around 265 births of babies with Down syndrome per year. This equates to approximately 1 in every 1,158 babies born in Australia, or about 1 in 1,100 according to another source.
The life expectancy of individuals with Down syndrome in Australia has significantly improved over the past five decades. On average, a person with Down syndrome in Australia can expect to live until the age of 60 or beyond. This increased longevity is attributed to improved healthcare and support services, such as the National Disability Insurance Scheme (NDIS). In 2019, over 10,000 individuals with Down syndrome were NDIS participants, and this number is expected to grow as the scheme expands its reach across Australia.
Down syndrome is typically diagnosed before birth, but in some cases, the diagnosis may be made after the baby is born. It is important for children with Down syndrome to have regular medical check-ups to monitor their health and manage any associated conditions. While Down syndrome is associated with cognitive impairment ranging from mild to severe, most children with this condition attend school, find employment, and lead happy and fulfilling lives as valued members of their communities.

Life expectancy for people with Down syndrome in Australia is 60 years of age
Down syndrome is the most commonly occurring chromosomal condition, and the most common genetic cause of intellectual disability. There is no national data collection on the number of people with Down syndrome in Australia, but the best estimate is that there were between 13,000-15,000 individuals with Down syndrome in the country as of 2019. This estimate is based on Western Australia data and, if accurate, means that for every 10,000 people, there are 5.14 people with Down syndrome. This prevalence is similar to other countries like the UK.
The life expectancy of people with Down syndrome has dramatically increased over the past 50 years, with the average life expectancy of a person with Down syndrome in Australia being 60 years of age. This is a significant increase, as by the year 2000, only 25% of people with Down syndrome in Western Australia had survived beyond 62 years of age. The increased life expectancy is likely due to improvements in general and medical care, including advances in the treatment of congenital heart disease and infections. As a result of these advancements, the majority of people with Down syndrome are now surviving into adulthood.
The average life expectancy of 60 years of age for people with Down syndrome in Australia is also influenced by certain factors that affect health and well-being. For example, women with Down syndrome experience early menopause, on average by the age of 45 years, which increases the risk of developing dementia. Additionally, people with Down syndrome are at a higher risk of osteoporosis.
The National Disability Insurance Scheme (NDIS) plays a crucial role in supporting individuals with Down syndrome and other disabilities in Australia. In 2019, there were over 10,000 people with Down syndrome registered with the NDIS, and this number is expected to grow as the scheme expands its reach across the country. The NDIS helps individuals with disabilities access the necessary support and resources to lead longer and healthier lives.
While the average life expectancy for people with Down syndrome in Australia is currently estimated at 60 years, there is potential for this to increase even further in the future. Research suggests that developments in preventative and modifying treatments for Alzheimer's disease could contribute to a further rise in life expectancy for individuals with Down syndrome, extending well beyond the current average of 60 years.
