There are many sources of data on people with disabilities. Unlike age or gender, ‘disability’ is not sharply defined. The definition of disability used varies considerably from one source of data to another, and different measures capture different aspects of disability. The measured disability rate is also affected by how the data are collected – whether it was self-assessed, based on a professional assessment or on qualifying for a particular type of support.
Sources of Data

Household surveys conducted by the Central Statistics Office have some information on people with disability. See in particular:
Quarterly National Household Survey modules on Disability in the labour force (Q2 2002), Disability Update (Q1 2004), and Equality (Q4 2004 and Q4 2010)

This survey follows a sample of older people (over 50s) at periodic intervals. The Intellectual Disability Supplement (IDS-TILDA) surveys a group of people with intellectual disability (aged initially over 40) at periodic intervals.
Some Data on Disability
The number of people recorded as having a disability is sensitive to what definition is used, and how it is measured. Unlike age or gender, ‘disability’ is not sharply defined. People’s perception of what constitutes a threshold of disability can also vary over time.
Census 2006 showed about 400,000 people reported a disability, or about 9% of the population. Census 2011 showed about 600,000 people reported having a disability, or about 13% of the population. There were some differences between the two censuses in how disability was measured.
