This can help government and others to make better decisions that affect people with an intellectual disability.

Gathering the evidence report
In October 2020, we made a report to the Disability Royal Commission on data and statistics about people with intellectual disability in Australia.
Our report includes data and information about:
- How many people in Australia have an intellectual disability
- Age, gender and cultural diversity
- Government supports
- Restricted decision making
- Schooling
- Employment
- Criminal justice
- Parents with intellectual disability
- Access to technology.
Our report also finds that there are many gaps in our information about people with intellectual disability in Australia.
These gaps make it hard to measure, report on, and improve outcomes for people with intellectual disability.
