While there could potentially be other migrant groups in Australia where pre-natal sex selection is taking place, SBS Radio's investigation focussed on the Chinese and the Indian communities.
SBS has obtained exclusive data which breaks down the number of boys and girls born to first generation Indian and Chinese parents between 2003 and 2013 in Australia.

Four demographers consulted by SBS agree the sex ratio at birth (SRB) data for babies born to Indian and Chinese parents shows skewed ratios.
Dr. Christophe Guilmoto, Demographer at the French Research Institute for Development in Paris and author of UNFPA report into gender preference; Dr. Nick Parr, Macquarie University’s Associate Professor in Demography; Dr. Gour Dasvarma, Flinders University’s Associate Professor in Population Studies; and Dr. Peter McDonald, Professor of Demography, Crawford School of Public Policy, College of Asia-Pacific, ANU, analised the ABS data.
The figures show the number of boys born compared to girls is unusually high for some overseas born parents in Australia: 109.5 boys for every 100 girls for Chinese-born Australians and 108.2 boys for every 100 girls for Indian-born Australians.
However, all Australian births during that 11 year period shows an average sex birth ratio of 105.7 males for every 100 females.
Dr Nick Parr tells SBS: “there has to be some form of sex selection taking place and the most plausible explanation is that there is sex selective abortion occurring”.
Associate Professor in Population Studies at Flinders University, Adelaide, Dr. Gour Dasvarma:

The size of these migrant groups is large enough to provide statistically significant data.
The Australian Bureau of Statistics (ABS) data includes 102,100 births (59% Indian and 41% Chinese), which exceeds the minimum of study cases requird to be statistically significant (40,000).
