Need for assistance
About this topic
Need for assistance measures people who report needing help with self-care, body movement, or communication because of a disability, a long-term health condition, or older age. It is a high-needs indicator rather than a general measure of disability.
This topic is useful for planning accessible facilities, care services, respite, and support for carers. The measure is based on self-report in the Census, so it should be interpreted with care and read alongside unpaid care and other disability-related indicators.
Interpretation notes
- The measure is self-reported and records need for help with core activities, so it is not a complete measure of disability prevalence.
- It applies to all persons and is strongest as an indicator of higher support need when read with unpaid care and ageing data.
