The Report found that records had been poorly kept; as such, there are statistics missing for some years. There are also no details about how or why the adoptions took place or whether the consent to adoption was given willingly. This means it is impossible to determine accurately how many of these adoptions were forced. Adoption rates fell after 1972, influenced by several factors, including the introduction of the Supporting Mothers Benefit (1973), wider availability of the contraceptive pill (1972), decriminalisation of abortion, and advancements in women’s rights.
These statistics are taken from the Senate Inquiry Report and show the number of adoptions that occurred per year in each Australian state and territory between 1939–40 and 2010.
