This report presents the 2010-11 data on the use of government-funded specialist homelessness services. It is the final annual report to be sourced from the Supported Accommodation Assistance Program (SAAP) National Data Collection (NDC). From 1 July 2011, data on the people using specialist homelessness services will be reported from the new Specialist Homelessness Services (SHS) collection. In 2010-11, an estimated 230,500 people (equivalent to 1 in 97 Australians) used specialist homelessness services. Young people, families and Aboriginal and Torres Strait Islander people continued to be significant users of services. The most common reasons why people sought support were interpersonal relationship issues (such as domestic or family violence); accommodation-related issues (such as being evicted); and financial issues (such as having insufficient money to pay for accommodation, food, bills or other essentials.
