The population of people with Down syndrome in Australia is now over 13,000.

As there is no national, state or territory register of Australians with Down syndrome (with the exception of the IDEA database in Western Australia) this number cannot be rigorously confirmed. However, Down Syndrome Australia is confident that our collation of what little data is available is accurate.

The number of Australian babies born per year with Down syndrome has been over 270 since 2007.

This number has been extrapolated from the recorded birth numbers from four states per the table on the DSA website (see links below). The calculation is based on the knowledge that the geographic spread of the population of people with Down syndrome matches that of the general population.
