    "description": "Most people assume that the leading cause of long-term disability is cancer, heart disease, or a serious accident. Musculoskeletal disorders — back pain, arthritis, degenerative disc disease, joint conditions — rarely come to mind as the top driver. The Council for Disability Awareness consistently finds musculoskeletal conditions responsible for roughly one-third of all long-term disability claims, making them the single largest category by a substantial margin. No survey directly measures what people guess the top cause to be, but the gap between public perception (accidents and cancer) and actual data (back and joint conditions) is documented across multiple insurer and advocacy sources.\n",

Step 1: SSA Fact Sheet states that just over 1 in 4 of today's 20-year-olds will become disabled (unable to work for 12+ months) before reaching normal retirement age (age 67). This implies a ~25% lifetime working disability probability. Step 2: CDA's long-term disability claims data finds musculoskeletal disorders account for approximately 29-30% of all LTD claims. Combining: 0.25 (lifetime disability probability) × 0.29 (musculoskeletal share of claims) ≈ 0.073. This chained estimate inherits uncertainty from both steps: the SSA figure is actuarial (includes all disabling conditions meeting SSDI criteria, not just employer LTD), and CDA's 29-30% figure is from insured employer LTD claims, a subset of all disabling events. The estimate is likely conservative for the broader disability definition and somewhat generous for the insured-LTD definition. Uncertainty range: 0.05-0.11.\n",

  "caveats": "The 7.3% lifetime figure is a chained estimate: SSA's actuarial 25% lifetime working disability probability × CDA's 29% musculoskeletal share of LTD claims. Both inputs carry uncertainty. The SSA figure is an actuarial projection for today's 20-year-olds entering the workforce; actual historical realized rates have varied. The CDA's 29% share is from insured employer LTD claims databases, which under-represent self-employed workers, informal workers, and workers without employer LTD coverage. The true population-level musculoskeletal disability rate is likely higher than 7.3% but less precisely documented because many musculoskeletal disabilities are managed without a formal LTD claim. \"Long-term disability claim\" as used here means a formal claim under an employer group LTD insurance policy, not including short-term disability, workers' compensation, or informal work absences. Back and neck conditions account for the majority of musculoskeletal LTD claims; arthritis and connective tissue disorders are the next largest sub-category.\n",
