Despite this significant and unprecedented investment, demographic factors are contributing to growing waiting lists for residential services, in particular, even though the number in receipt of services, including full-time residential services, continues to increase. The increased birth rate in the 1960s and 1970s has resulted in large numbers of adults in their late twenties and early thirties requiring full-time residential services. In addition, people with an intellectual disability are living longer than previously, adding to the need for services compared to previous generations. This has also been the international experience in service provision to this population.
