Neither absolute nor relative inequalities in employment outcomes changed and relative inequalities for NILF widened over time. People with disability were 30% to 40% less likely to be employed, 1.4 to 2.7 times more likely to be unemployed and 2.0 to 2.8 times more likely to be NILF compared with people without disability. The greatest relative inequalities in employment were experienced by older working-age people with disability, people with intellectual or learning disability, brain injury or stroke and psychological disability.</p><p><strong>Conclusions: </strong>This descriptive study adds to previous findings showing employment inequalities by demonstrating that disability-related inequalities in employment have been sustained for two decades in Australia without improvement. As a key social determinant of health, the findings are a critical public health concern.</p>","PeriodicalId":19459,"journal":{"name":"Occupational and Environmental Medicine","volume":" ","pages":"251-260"},"PeriodicalIF":3.2,"publicationDate":"2026-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13539861/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148620768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
